    • Update German resources.

    [1.1.6] - 2009-3-9

    Added

    • Add PCI / PCIe bus benchmark to tools menu. This tool allows you to measure the transfer rate from AlazarTech digitizer boards to host memory. It may be useful to verify that your PC is capable of the sustained transfer rates required for streaming. Note that this tool can be used with the following boards: ATS460, ATS660, ATS860, or ATS9462 with FPGA version 23 or above. Other boards lack firmware required for its operation.
    • Add a splash screen on program startup. The splash screen is displayed during board initialization, which may take many seconds depending on the number and type of boards in your board system.

    • Fix an error in section 4.10.3 of the "AlazarDSO User Guide" that incorrectly stated that CAPTURE_BUFFER structures were written to an ATB file when CFHF_STREAM flag is set in the file header. Only the sample data stored in CAPTURE_BUFFER structures are written to file.

    [1.1.2] - 2009-1-29

    Added

    • Add "Interpolate trigger position" to the "Configure Oscilloscope View" dialog. This feature helps improve the display of repetitive signals at horizontal scales that allow you to resolve sample points. The trigger position normally has a jitter of one-sample since trigger events may occur at any time between sample points. This jitter causes the trigger position in a repetitive signal to appear to shift horizontally by up to one sample point. When the "Interpolate trigger position" option is enabled, AlazarDSO calculates the trigger position in between sample points, and displays this sub-sample trigger position at the trigger marker on screen. This results in the stable display of repetitive signals by removing the one-sample jitter.
    • Add "Enable AUX I/O trigger enable" to the "Configure Trigger" dialog. This option allows you to configure a board to wait for an external enable event before enabling its trigger engines. This may be useful, for example, in scanning applications where you wish to capture scan lines only after a "start of frame" event.
    • Remove "number of acquisitions" from the "Set multiple record options" page of the "Stream to Disk" wizard. This simplifies the configuration of multiple-record streaming acquisitions. It also prevents the common error of specifying multiple acquisitions when multiple "transfers per acquisition" was really desired.
    • Add page numbers to "Stream to Disk" wizard property sheet pages. This change should make it easier to identify pages in the wizard.
    • Add the "Markers" line style to "Configure Input", "Configure Math", and "Configure Reference" dialog boxes. This option may be useful if you wish to view sample points without line segments between them.
    • Change the simulator to add slew to square waves, and trigger phase error to all waveforms. This change allows the simulator to generate signals that have one-sample trigger jitter

    Fixed

    • Fix a bug in the simulator that resulted in incorrect simulated non-interleaved AutoDMA records with pre-trigger samples when multiple records per transfer were requested.

    [1.1.1] - 2009-1-15

    Added

    • Change default action on double-clicking the "Plugin" text in the graticule to show the configuration dialog of the currently selected plugin.
    • Add an option to disable checking for signal out of range.

    Fixed

    • Fix a bug where the number of samples per channel was incorrectly calculated on loading ATB files in multi-board systems. This resulted in error 653 in the log file, and partial data displayed using the "Browse Records" dialog.

    [1.1.0] - 2009-1-6

    Added

    • Add the "limit memory allocated per channel" option to improve program functionality under 32-bit Windows with board systems that have 128 MS or more of on-board memory per channel. Previous versions required 64-bit Windows to work with such systems.
    • Add a "Signal out of range" warning if a signal is greater than a channel's input range.
    • Add UP ARROW, DOWN ARROW, CTRL+UP ARROW, and CTRL+DOWN ARROW keyboard shortcuts to navigate between records in a multiple record capture.
    • Add LEFT ARROW, RIGHT ARROW, HOME, PAGE UP, PAGE DOWN, CTRL+LEFT ARROW, and CTRL+RIGHT ARROW keyboard shortcuts to navigate within a record of a capture.

    Fixed

    • Change the "Configure" menu "Load..." and "Load Recent" commands to copy settings from the selected file to a working configuration file rather than using the selected file as the working configuration file.
    • Fix a bug that might cause an invalid memory access error if a plugin was active while switching between board systems.
    • Fix a bug where "automatically set memory options" claims to disable "capture during display" but the program continues to use "capture during display" anyway.

    [1.0.22] - 2008-12-14

    Fixed

    • Fix a bug in the "Stream To Disk" wizard where selecting "multiple record" type acquisitions would result in buffer overflow errors when saving to disk.

    [5.8.1] - 2011-3-16

    Added

    • Support for ATS9870 Master/Slave board configurations.

    Fixed

    • Bug that causes `AlazarSetCaptureClock()` to return `ApiInvalidData` when 10 MHz external PLL mode was selected.

    Added

    • Supports 50 or 300 ohm external trigger impedance with hardware revision 1.3.
    • `SET_EXT_TRIG_IMPEDANCE` to `AlazarSetParameter()` to control external trigger impedance.

    Fixed

    • Bug introduced in version 5.7.18 of the DLL (ATSApi.dll) that might generate an `ApiDmaInProgress` error from `AlazarReadEx()` if it was called after calling `AlazarAbortAsyncRead()`.
    • Bug in the DLL (ATSApi.dll) that would cause `AlazarBeforeAsyncRead()` to return `ApiLockAndProbePagesFailed` if the `ADMA_ALLOC_BUFFERS` flag was set and the number of buffers was increased since the last call to `AlazarBeforeAsyncRead()`.

    [5.7.19] - 2010-8-20

    Added

    • `AlazarSetTriggerOperationForScanning()` for OCT applications using external clock and trigger inputs where the external clock signal becomes unsuitable to drive the digitizer between scan lines. Use this option to delay start of an acquisition until an external trigger event when the clock is stable.

    [5.7.17] - 2010-8-11

    Fixed

    • Bug that resulted in incorrect sample rates on the slaves of an ATS9350 Master/Slave configuration.

    [5.7.16] - 2010-8-10

    Added

    • Support for ATS9350 Master/Slave configuration.
    • Change `AlazarSetCaptureClock()` to add support for selecting rising or falling edge of external clock inputs.

    [5.7.15] - 2010-7-20

    Fixed

    • Bug where LED 13 lights up on driver download.

    [5.7.14] - 2010-6-22

    Added

    • `AlazazarSetClockSwitchOver()` which allows scanning applications using an external clock input to switch to an internal "dummy" clock during re-trace intervals if the external clock signal is not suitable to drive the ADCs during re-trace internvals.
    • Allows driver to control SPI communication with VCO only when FPGA versions 14.9, 14.10 or 14.11 are installed.

    [5.7.13] - 2010-6-17

    Added

    • Allows driver to control SPI communication with VCO when FPGA version 14.9 or later is installed.
    • Version 5.7.13 allows driver to control SPI communication with VCO when FPGA version 14.9 or later is installed.

    [5.7.12] - 2010-5-20

    Fixed

    • ATS460-8M bug that resulted in ApiBufferOverflow errors in streaming AutoDMA modes when the number of samples per AutoDMA buffer was 4M or greater.
    • Bug that caused `AlazarHyperDisp()` to return `ApiUnsupportedFunction` even if supported by the firmware.
    • Bug that resulted in `ApiBufferOverflow` errors in streaming AutoDMA modes when the number of samples per AutoDMA buffer was 4M or greater.
    • Bug that caused AlazarHyperDisp to return ApiUnsupportedFunction even if supported by the firmware.

    Changed

    • Change VCO parameters in the ATS9350.sys file to reduce spurious noise levels.

    [5.7.11] - 2010-4-21

    Fixed

    • Bug in version 5.7.10, where the driver installation program installed an incorrect version of the FPGA image. Version 5.7.11 installs the correct FPGA image A6110242.ali.

    Added

    • Support to `AlazarGetNextAsyncBuffer()` with the `ADMA_GET_PROCESSED` flag to return an array 32-bit signed data from ATS9870 boards with autocorrelation firmware.

    Changed

    • Installs the FPGA image A6110242.ali.

    [5.7.10] - 2010-3-31

    Added

    • `AlazarErrorToText()` to convert return code to strings.
    • `AlazarSetExternalClockLevel()` function to allow setting the external clock comparator level. This function replaces using `AlazarSetParameterUL()` with the `SEND_DAC` parameter.

    Fixed

    • Bug where `AlazarStartCapture()` may return `ApiNotSuppotedInDualChannel` Mode with Continuous AutoDMA transfers.
    • Bug affecting stability in "10 MHz PLL" external clock mode.

    Changed

    • `AlazarHyperDisp()` to support ATS9462.
    • `AlazarHyperDispEx()` to work with 64-bit transfer offsets.
    • `AlazarHyperDispEx()` to check FPGA version of PCIe devices for HyperDisp support and retun `ApiUnsupportedCommand` if it is not available with the FPGA version. The ATS9350 requires FPGA version 13.6. The ATS9462 requires FPGA version 33.1. The ATS9870 requires FPGA version 34.13.

    [5.7.8] - 2010-2-1

    Added

    • Support for the version C silicon of the ADC chip used on ATS9870. In this version, driver automatically detects the silicon version and sets timing parameters so data can be acquired correctly irrespective of the silicon version. Previous driver versions would have set timing parameters for version B silicon, which has now been discontinued by the manufacturer. If an older driver were used with version C silicon, user may have seen glitches on one or both channels.

    Fixed

    • Bug in version 5.7.7 where the 10 MHz PLL clock is not set properly.

    [5.7.7] - 2010-1-1

    Added

    • `GET_MAX_PRETRIGGER_SAMPLES` property to `AlazarGetParameterUL()` to allow applications to determine the maximum number of pre-trigger samples supported by a board.

    [5.7.6] - 2009-12-1

    Added

    • Initial release of Windows driver for ATS9350.
    • Initial release of Windows driver for ATS9850.
    • Initial release of Linux driver for ATS9350.
    • Initial release of Linux driver for ATS9850.
    • `AlazarConfigureAuxIo()` function to allow applications to setup the AUX I/O.

    Fixed

    • Bug in continuous streaming where `AlazarWaitAsyncBufferComplete` would fail with `ApiWaitTimeout` unless `AlazarSetRecordSize()` was called before calling `AlazarStartCapture()`.

    Changed

    • New FPGA images, A6110242.ali and A6210242.ali, which allows Trigger Output on the AUX I/O connector of v1.3 boards.

    [5.7.5] - 2009-11-1

    Added

    • Disk streaming API, whereby all streaming operations are handled by the AlazarTech DLL.

    Changed

    • Properly supports "10 MHz PLL" external clock mode.
    • `AlazarWaitNextAsyncBufferComplete()` to not copy data back to user buffer, if buffer length is zero. Previous versions required that both the buffer be zero and NULL. This was problematic in environments such as LabVIEW.
    • `AlazarSetExternalTrigger()` to disable support for AC-coupled external trigger. The value it now returns is `ApiNotSupportedThisChannel`.

    [5.7.4] - 2009-10-1

    Changed

    • Modify `AlazarWaitAsyncBufferComplete()` to return `ApiBufferOverflow` rather than `ApiFailed` when it detects a buffer overflow error. This is particularly important improvement for LabVIEW vi's.

    [5.7.3] - 2009-9-1

    Added

    • `AlazarReadEx` to allow 64-bit "trigger offset" values for the ATS9870 boards with more than 2G samples per channel of on-board memory.

    Fixed

    • Bug in which a value written to the analog CPLD may result in `AlazarStartCapture()` returning `ApiPllNotLocked` error.

    [5.7.2] - 2009-8-1

    Added

    • `ADMA_GET_PROCESSED_DATA` flag to AdmaFlags in `AlazarBeforeAsyncRead()`. Setting this flag allows AlazarGetNextAsyncBuffer (used by LabVIEW vi's) to copy data into the user buffer in a consistent format. Note, however, that this involves data manipulation by the CPU, so data intensive applications may prefer to use raw data buffers and interpret them accordingly.

    Changed

    • Version 5.7.2 is highly recommended to be used with firmware version 31 or higher. Older firmware versions do not include an error correction circuit (ECC) that is required by the ADC chip. Without this ECC, signal integrity can be compromised.
    • Disables Gray code data output from the ADC chip. This is done because the ADC manufacturer plans to remove this option from future versions of silicon.

    [5.7.1] - 2009-7-1

    Added

    • Initial release of Windows driver for ATS9870.
    • Initial release of Linux driver for ATS9870.

    [5.7.0] - 2009-6-1

    Added

    • Support for ATS9462 with on-board memory.

    Fixed

    • Bug that caused the reported memory size from `AlazarGetParameter()` (MEM_SIZE) to return 0 after calling `AlazarReadEEprom()`.

    [5.6.15] - 2009-5-1

    Added

    • Change `SETGET_ASYNC_BUFFCOUNT` to allow less than 3 buffers.

    [5.6.14] - 2009-4-1

    Fixed

    • Bug that caused incorrect triggerring in NPT mode with both channels enabled and the AUX I/O trigger enable input enabled.

    [5.6.13] - 2009-3-1

    Fixed

    • Bug in version 5.6.12, where the driver installation program installed an older version (v5.6.11) of the device driver file (ATS9462.sys).

    [5.6.12] - 2009-2-1

    Added

    • There are no new capabilities for the ATS330 in driver version 5.6.11
    • Allow signed data output in addition to the existing unsigned format. This FPGA also implements special timing circuitry to handle active SyncBoard 460 x4 for Master/Slave systems of up to 4 boards.
    • There are no new capabilities for the ATS860 in driver version 5.6.12

    Fixed

    • Bug in `AlazarSetCaptureClock()` that resulted in `ApiPllNotLocked` errors in master-slave board systems onfigured to use an external clock input.
    • Workaround for a bug in firmware version 23 that intermittently caused the AlazarDSO bus benchmark test to return an `ApiBufferOverflow` error.

    Changed

    • New FPGA images, A6110240.ali and A6210240.ali, which allow signed data output in addition to the existing unsigned format.

    [5.6.11] - 2009-1-1

    Added

    • FPGA version to allow the programmer to control whether the ATS860 output data is unsigned binary (default) or signed.

    Fixed

    • Bug in previous versions for Master/Slave operation of multiple ATS860s. In previous versions, slave board(s) could have a +/- 1 point (2-point peak to peak) trigger jitter at 250 MS/s rate. With the updated FPGA, slave boards now have the same trigger jitter as the Master board, +/- 0.5 point (1-point peak to peak) jitter.
    • Bug in `AbortAsyncRead()` where the function might fail when called in NPT mode. The PC would have to be rebooted to recover from this error.

    [5.6.10] - 2008-12-1

    Changed

    • Modify driver to detect buffer overflow after asynchronous transfer. Previous version did not check for this overflow and could have displayed bad data in AlazarDSO. This problem becomes more pronounced on slower computers and longer (> 40 K) buffers.
    • Change `AlazarAbortAsyncRead()` for ATS9462 with FPGA version 23 or greater to assert DREQ until DMA completes rather than using `AlazarAbortCapture()`. This is very useful if ATS9462 is supposed to be clocked by an external clock, but no external clock is supplied. Previous versions would have locked up the computer, needing a power cycle.

    [5.6.9] - 2008-11-1

    Fixed

    • Bug in previous versions that could have caused LabVIEW vis to stop working (ApiWaitTimeout error in AsyncDMA.vi) until the PC was rebooted. This bug was caused by an incomplete clean-up of DMA buffers that had been queued up.

    Changed

    • Reports an error if user selects 180 MS/s or 160 MS/s sample rate and the on-board PLL does not lock.

    [5.6.7] - 2008-10-1

    Fixed

    • Bug in `AlazarAbortAsyncRead()` in continuous or triggered mode where the in-progress DMA was not aborted. The PC would have to be rebooted to recover from this error.
    • Bug in AlazarRead that might lock PLL.
    • Bug in AlazarAbortAsyncRead in continuous or triggered mode where the in-progress DMA was not aborted. The PC would have to be rebooted to recover from this error.
    • Bug which may have caused the two inputs channels to appear to be offset by one sample.
    • Bug that may have caused AutoDMA acquisitions for Traditional DMA (non-NPT) to stall if RecordsPerBuffer was set to 1 and RecordCount was set to 1.
    • Bug that could have caused Slow External Clock to not work as it should.

    [5.6.6] - 2008-9-1

    Fixed

    • Bug in the driver that could have caused a lockup of the computer at very high trigger repeat rates. The lockup may have exhibited itself by freezing the mouse and keyboard or by simply stalling the acquisition.

    [5.6.5] - 2008-8-1

    Fixed

    • Bug introduced in version 5.6.4 that caused DMA transfers to fail in LabVIEW VIs.
    • Full support for 64 bit scatter-gather lists. Previous versions did not fully support 64-bit addressing, causing some reduction in data throughput on 64-bit computers with greater than 4 GB memory.

    [5.6.4] - 2008-7-1

    Fixed

    • Bug in previous versions that could have caused on-board DMA state machine to lock up in DmaPaused or DmaInProgress states. The accompanying FPGA files allow unconditional completion of an in-progress DMA in order to avoid this error.
    • Bug in previous versions whereby if user attempts to do a No-Pre-trigger (NPT) acquisition using Asynchronous DMA after having done an acquisition with "Enable Headers", the first 16 points of the NPT data were corrupted. Version 5.6.4 resets the "Enable Headers" bit properly when doing an NPT acquisition.

    [5.6.3] - 2008-6-1

    Fixed

    • Bug that NPT and Traditional Synch/AsyncDMA would fail if the user was previously using Continuous Streaming or Triggered Streaming. The trigger settings were not being restored properly.
    • The accompanying A6110237.ALI and A6210237.ALI FPGA images fix a bug in previous versions that could have possibly caused the DMA engine to lock up when a user initiated an abort.
    • Bug in NPT DMA mode. This bug caused data corruption at the end of data buffers returned by ATS860.
    • Bug in API `AlazarAbortAsyncRead()`, that prevented the NPT AsyncDMA from completing the DMA when an external clock was being used and the clock stopped.

    [5.6.1] - 2008-5-1

    Fixed

    • Bug which could have prevented the full DMA transfer from completing for NPT AutoDMA transfers.
    • Bug in the WinXP64, and Windows Vista X64 drivers that stalled the Asynchronous DMA acquisition process from completing the capture, due to a compiler optimization.

    [5.6.0] - 2008-4-1

    Added

    • Setup.exe installation program to distribute the driver.

    Fixed

    • Previous versions of the driver could have caused data integrity problems with some SODIMMs used on ATS460-128M. Version 5.6.0 introduces new FPGA images, A6110236.ali and A6210236.ali, that fix this bug by running the on-board memory at 100 MHz clock frequency.
    • Bug where API `AlazarQueryCapability()` presented the device serial number in an incorrect format; the device-type digit was missing. The ATS9462 device-type digit is "9", and therefore all serial numbers should start with a "9" and be greater the 900000. Customers owning an ATS9462 should not be concerned as the device EEPROM does hold the correct value. Only the `AlazarQueryCapability()` API was affected.

    Changed

    • Apis, `AlazarSetParameter()`, `AlazarGetParameter()`, `AlazarSetParameterUL()`, and `AlazarGetParameterUL()` are documented.
    • Asynchronous AutoDMA applications using the `AlazarWaitNextAsyncBufferComplete()` API, (mostly used in LabView) can sense if an overflow situation is about to occur, and selectively discard data buffers in order to safe guard from overflowing.
    • ATSApi.dll now indicates the architecture type in the Product Description field of the files property page. This is used to easily distinguish the x64 architecture SDK dll from the x32 architecture sdk dll. To view this information, Right-Button click on the dll file, select the Properties menu item and click the Version tab.

    [5.5.3] - 2008-3-1

    Fixed

    • Bug in previous versions that caused LabVIEW VIs to hang if user stopped the VI and tried to restart it. Previous drivers used to report a wrong value for on-board memory for ATS9462 when a VI was run after being stopped. This resulted in wrong calculation of DMA buffer length, causing a PC hang-up. Version 5.5.3 reports the same, correct, value no matter how many times a vi is started or stopped.
    • Bug in previous versions that caused LabVIEW VI to hang if user tried to stop an acquisition in Triggered Streaming mode. In previous versions, dll code would end up in an infinite loop when a Triggered Streaming acquisition was stopped. Fixes this bug by avoiding the infinite loop.
    • Bug in previous versions that caused LabVIEW vis to not trigger properly in NPT mode if user had previously used Continuous Streaming or Triggered Streaming mode. In effect, once the vi was put in either Continuous Streaming or Triggered Streaming mode (by internally setting the "Continuous Mode" bit to "1"), it could never come out of the mode unless the PC was re-booted, i.e. the "Continuous Mode" bit was never reset to 0 when NPT mode was selected. Version 5.5.3 fixes this bug by properly resetting the "Continuous Mode" bit when NPT mode is selected.
    • Bug in previous versions that caused ASoPC signature to return a hexadecimal value of 0xC for on-board memory bits, i.e. bits 15 down to 12. This could have been interpreted by some application programs as the ATS9462 having 128 Meg per channel of on-board memory. Version 5.5.3 fixes this problem by reporting a value of 0x0 for bits 15 down to 12 of the ASoPC signature
    • Memory leak in GetNextAsyncBuffer API call used by LabVIEW.

    [5.5.2] - 2008-2-1

    Fixed

    • code to go into an infinite loop for NPT AsyncDMA with finite number of triggers.

    [5.5.1] - 2008-1-1

    Added

    • Two new API functions: `AlazarStopAutoDMA()` and `AlazarFlushAutoDMA()`. These functions can be called if the user is capturing data using AutoDMA (synchronous DMA) and triggers stop coming. `AlazarStopAutoDMA()` stops any further DMAs from being started. This function should be called before `AlazarFlushAutoDMA()`. `AlazarFlushAutoDMA()` generates the required number of software triggers to complete the current DMA, thereby guaranteeing an orderly end of the acquisition session despite the lack of user-supplied triggers.

    Fixed

    • Bug in V5.5.0 that did not allow asynchronous DMA on ATS660. Starting with V5.5.1, ATS660 has full asynchronous DMA capability.
    • Bug in V5.5.0 which did not allow the calibration EEPROM to be updated.
    • Bug in `AlazarAbortAsyncRead()` that could have caused false buffer overflow error. This overflow error would have appeared if the user had set infinite number of records, stopped the acquisition manually and then tried to start another acquisition.

    [5.5.0] - 2007-12-1

    Added

    • Initial release of Windows driver for ATS9462.
    • Support for helper functions for asynchronous DMA from ATS860 to host PC memory using overlapped I/O.

    Fixed

    • Bug in `AlazarGetNextAutoDMABuffer()` routine. In version 5.4.0 of the driver, this routine was returning only half the data in No-Pre-Trigger (NPT) mode.
    • Bug in previous versions that caused the driver not to load under Windows 2000.

    [5.4.0] - 2007-11-1

    Added

    • Full Vista power management compliance, i.e. it fixes a power state handling bug in previous versions, which caused a Vista-based PC to crash if it was powered down with the ATSxxx driver loaded. In some machines, this crash caused a re-boot.
    • Full support for No-Pre-Trigger (NPT) operations for ATS860. These features were not available in previous versions.
    • Full support for asynchronous DMA from board to host PC memory using overlapped I/O. Overlapped I/O, (IO completion ports) are a high performance means of reading and writing simultaneously on the same socket. It is managed at system level, thus offering maximum performance. This technique has only been available since the advent of Winsock 2.0 in Windows NT, 2000, and XP. Note that this feature is not supported under Windows 98 SE. This is the highest performance dma possible under Windows, as the CPU usage stays at 0% even if data throughput is 100 MB/s. Some new API calls have been introduced in this version to allow asynchronous dma's: - `AlazarBeforeAsyncRead()` - `AlazarAsyncRead()` - `AlazarAbortAsyncRead()`

    Fixed

    • Bug whereby a single-ported data transfer (using AlazarRead) that was greater than 4 Megabytes, would return corrupted data.

    Changed

    • Use the same integrated memory controller as ATS460 and ATS660, allowing greater reliability and faster throughput.

    [5.3.3] - 2007-10-1

    Changed

    • No user visible change.

    [5.3.2] - 2007-9-1

    Changed

    • No user visible change.

    [5.3.0] - 2007-8-1

    Added

    • Ability to adjust the external clock reference voltage using `AlazarDACSettingAdjust()`.

    Fixed

    • Bug in all previous v5.x.x drivers, whereby `AlazarGetNextAutoDMABuffer()` did not return code 513 when the last buffer was received. This could have resulted in acquiring an extra buffer containing bad data at the end of the acquisition.

    Changed

    • Use a new, highly integrated memory control logic that improves data throughput and reliability. Note that this new logic increases power consumption by approximatively 10%.

    [5.2.0] - 2007-7-1

    Added

    • WOW support, allowing 32 bit applications to call 64 bit driver. Installation of WOW drivers is done simultaneously with the 64-bit driver installation.
    • 64 bit driver for ATS330.
    • 64 bit driver for ATS660.
    • 64 bit driver for ATS850.
    • 64 bit driver for ATS860.

    Changed

    • Install AlazarTech products in their own class in Device Manager. The ClassName is "AlazarTech PCI Digitizers".

    [5.1.2] - 2007-6-1

    Fixed

    • Bug in the AtsApi.DLL that did not allow dual channel operation in No-Pre-Trigger AutoDMA mode.

    [5.1.1] - 2007-5-1

    Fixed

    • Bug in the AtsApi.DLL that did not allow the number of records for Master/Slave configurations to be greater than 1000.
    • Problem in the trigger engine firmware that may have caused faulty triggering in a Master/Slave configuration using more than 1000 triggers in the Traditional acquisition mode.

    [5.1.0] - 2007-4-1

    Added

    • Support for Non-Pretrigger AutoDMA in both Dual and Single channel modes.

    [4.9.8] - 2007-3-1

    Added

    • Allows programmers to read the serial number and other board-specific information using AlazarQueryCapability API call.
    • Allows programmers to use AlazarRead API call even after an AutoDMA session. In previous versions, some of the AutoDMA related bits were not being reset at the end of an AutoDMA, causing Traditional API's such as AlazarRead to fail.

    Fixed

    • Bug introduced in Version 4.9.3 whereby non-AutoDMA acquisitions with greater than 1000 triggers produced faulty data. This fix is done in the new FPGA firmware.
    • Bug found in all previous versions that caused needless relay switching. This bug typically exhibited itself when either the Input Range was changed or a new capture was started.

    [4.9.7] - 2007-2-1

    Added

    • Support for "10 MHz PLL Reference" clock for ATS660. User is able to multiply the externally supplied 10 MHz reference frequency to produce a 110 MHz to 130 MHz sampling clock.
    • AC-coupled external clocking (non-PLL). In previous versions AC-coupled clocks were not properly biased. Starting with Version 4.9.7, an on-board DAC is used to provide a 1.5V self-bias for an on-board comparator, thereby allowing external clock signals up to +/- 1V to be used
    • Allows `AlazarGetStatus()` to return whether or not the 10 MHz PLL is locked or not.
    • Allows a program to read the serial number and last calibration date of the card(s) in the system using `AlazarQueryCapability()`.

    Fixed

    • Bug in Version 4.9.5 for ATS660 Master/Slave systems, which did not allow proper synchronization of all channels.
    • Bug in version 4.8.5 to 4.9.6 that caused Slave boards to be stuck at the alternate oscillator frequency (100 MS/s on ATS660) if Master was clocked at a rate lower than the alternate oscillator frequency (e.g. 50 MS/s on ATS660). Now, all boards are clocked at the same frequency.

    [4.9.6] - 2007-1-1

    Added

    • Allows NPT AutoDMA to work with optional Trigger Enable. Previous versions did not allow the two modes to operate together.

    [4.9.5] - 2006-12-1

    Fixed

    • Bug in Version 4.9.4 that caused intermittant failure of AlazarRead. This bug exhibited itself by seeming to swap data between channels A and B when displaying in API Panel.
    • Bug in V4.9.4 that loaded the wrong FPGA for ATS660-128M, causing various errors.

    [4.9.4] - 2006-11-1

    Added

    • Initial release of Windows driver for ATS660.
    • Initial release of Windows driver for ATS860.

    Fixed

    • Bug in Version 4.9.3 that did not allow NPT AutoDMA to work in dual channel mode.

    [4.9.3] - 2006-10-1

    Changed

    • Resets the ATS460 upon exit. This resolves the bug that could have caused a bugcheck (blue screen) when the application was closed.
    • The firmware accompanying Version 4.9.3 also has improved and pipelined interface for PCI bus. Some of the previous firmware versions caused some PCs to freeze while data was being transferred.

    [4.9.2] - 2006-9-1

    Fixed

    • Bug in AutoDMA that caused one Pre-Trigger sample to be read if user had set Pre-Trigger depth to be 0.
    • Bug that caused occasional 8 point trigger jitter at very high trigger repeat rates.

    [4.9.1] - 2006-8-1

    [4.9.0] - 2006-7-1

    Fixed

    • Bug in the installation INF file that now overwrites registry values when a driver is upgraded. This is particularly useful for customers upgrading from ATS310-128K or ATS330-128K to ATS310-8M or ATS330-8M. Previous versions did not update the maximum buffer size key in the registry, causing a DMA failure message to be generated. Note this error applies only to ATS310 and ATS330 users.
    • Some kernel level driver errors that could have been generated in some PCs that do strict power management.

    Added

    • Full support for Data Record Headers for AutoDMA transfers. Users can now obtain information such as Time Stamp, Record Number, Who Triggered etc. for each of the records captured using AutoDMA. This makes it very easy to find out if any of the triggers was missed or not and also to obtain the arrival time of each trigger.

    [4.8.7] - 2006-6-1

    Added

    • Allow the user to acquire up to 256,000 triggers into on-board memory. Previously, this limit was 1000 triggers. As before, both pre-trigger and post-trigger points can be captured for each of the records. A 40-bit timestamp value is also recorded for each of the records.

    [4.8.6] - 2006-5-1

    Fixed

    • Bug that caused DMA Overflow flag to be falsely asserted when capturing both channels in continuous capture (PCI streaming) mode.

    [4.8.5] - 2006-4-1

    Added

    • Full support for the PCI Streaming mode. In previous versions of the driver, DMA Overflow flag was not properly read, resulting in false positives.

    Fixed

    • Bug for AutoDMA transfers that could have cause one of the FIFOs to overflow at high trigger rates, causing a data dropout.

    [4.8.1] - 2006-3-1

    Fixed

    • Bug for ATS310-8M, which did not allow triggering with negative slope.
    • Bug for ATS310-128K, which did not allow proper operation at sampling rates other than 20 MS/s.
    • Bug for ATS330-128K, which did not allow proper operation at sampling rates other than 50 MS/s.
    • Bug for non-AutoDMA transfers (using AlazarRead) that could have caused a failure in the AlazarRead operation, resulting in the system freezing.

    [4.8.0] - 2006-2-1

    Fixed

    • Bug for AutoDMA transfers that could have caused data corruption if RecsPerBuf was set to value for which bits 7 or 8 were '1'. For example, a setting of RecsPerBuf = 64 in dual channel mode (or 128 in single-channel mode) could have caused intermittant data corruption. Customers MUST upgrade to V4.8.0 driver, as the fix requires a new FPGA image (*.ALI file) and a new DLL. Do NOT simply copy the FPGA file to its destination folder, as it will not work with any of the older DLL files.
    • Bug in setting Trigger Timeout. In previous versions, if Timeout was set to a value of 1 (one), the system would not wait for all pre-trigger points to be captured before issuing a Timeout Trigger. In version 4.8.0, if a Timeout value of 1 (one) is set, the DLL will automatically promote that value to 2.

    [4.7.1] - 2006-1-1

    Added

    • Allow any Slave ATS460 in a Master/Slave system to trigger the system. Previous version (V4.7.0) only allowed the Master board to trigger the system.

    Fixed

    • Bug in trigger address calculation for AutoDMA transfers. Previous versions of ATS460 driver may have miscalculated the trigger address by as many as 16 points.

    Changed

    • Dual channel AutoDMA transfers have been made more reliable in V4.7.1. Previous versions sometimes caused wrong data to be captured for overall data transfer greater than 8 Million samples.
    • Issue a reset signal to the PCI interface circuit when the ATSApi or ATSApiVB DLL is loaded.
    • ATSApi and ATSApiVB DLLs no longer try to activate drivers named PCI9052, PCI9054, PCI9056, PCI9656. This could have caused a conflict with other PCI boards that used these interface chips and did not rename their driver name.

    [4.7.0] - 2005-12-1

    Added

    • Support 128 MegaSamples acquisition memory for ATS460.
    • Allow the TRIG OUT connector to be reconfigured as TRIGGER ENABLE input. Note that a hardware modification is required to make this change.

    Fixed

    • Previous versions of ATS460 driver were susceptible to not triggering on Channel A or Channel B when negative slope was selected. Version 4.7.0 fixes this bug.
    • Bug introduced in version 4.6.5, which caused ATS460 to not be recognized in some PCs. This was caused by improper downloading of the FPGA image.
    • Bug in Dual channel AutoDMA transfers which sometimes produced spurious data.

    [4.6.5] - 2005-11-1

    Added

    • More redundant FPGA download scheme that returns an error if the expected FPGA file is not found.
    • Allows custom FPGAs to be downloaded for OEM customers.

    Fixed

    • Bug which caused ATS310, ATS330 and ATS460 to freeze in some PCs.

    [4.6.4] - 2005-10-1

    Added

    • ATS460 V1.2 board support for larger FPGA. Note that previous versions of the driver will cause the PC to freeze upon start-up if v1.2 hardware is found. This is because the FPGA image supplied with the older drivers cannot be loaded into the V1.2 FPGA.

    Fixed

    • Trigger-related bug introduced in v4.6.3 for ATS310-128K.
    • Trigger-related bug introduced in v4.6.1 and v4.6.3 for ATS330-128K.

    [4.6.3] - 2005-9-1

    Added

    • Initial release of Windows driver for ATS310-8M
    • Initial release of Windows driver for ATS330-8M.

    Fixed

    • Bug in AutoDMA operation that could cause the ATS460 to freeze during very high trigger repeat rates (~ 8 KHz). System monitoring has been added to guarantee no lock-ups even at extreme trigger rates.
    • Updates the firmware for ATS460 in order to improve trigger stability. V4.6.1 firmware exhibited as much as 8 sample point trigger jitter under accelerated temperature cycling.

    [4.6.1] - 2005-8-1

    Added

    • Digital triggering on the ATS330-128K. This type of triggering is much more accurate than analog triggering.
    • Support for Optional Trigger Out functionality on v1.3 ATS850 hardware. If an ATS850 unit is equipped with Trigger Out upgrade, the ECLK BNC connector, fourth fromt he top, is used for outputting a 5V TTL Trigger signal. When used in conjunction with Trigger Delay, Trigger Out signal is asserted as soon as a trigger condition is detected. This is useful for ultrasonic applications that require a pulser-receiver to be triggered at time t = 0, but ATS850 sampling to start at a later time, say t = 800 sample clocks. Note that Trigger Out is always synchronized to the sampling clock.

    Changed

    • The Trigger Out functionality of the ATS460 when used in conjunction with Trigger Delay. Previously, Trigger Out signal was asserted after the delay had expired. Starting from this version, Trigger Out is asserted as soon as a trigger is detected, i.e. before the trigger delay has expired.

    [4.6.0] - 2005-7-1

    Added

    • Supports the Dual Port Memory Upgrade and fully implements the advanced AutoDMA capability of the ATS460, whereby users can capture data based on rapidly occuring trigger events (also known as Hi-PRF Capture) at rates as high as 2 KHz for records as long as 2048 samples.

    [4.5.2] - 2005-6-1

    Fixed

    • Correctly implements the `AlazarGetChannelInfo()` API call and returns correct on-board memory in samples. Previous versions always returned 256K.

    Changed

    • Powers down the on-board ADC chips when the DLL is closed, i.e. when the ATS460 is not being used. This is done to improve energy savings and reduce power consumption.

    [4.5.1] - 2005-5-1

    Added

    • Initial release of Windows driver for ATS460.

    [4.4.0] - 2005-4-1

    Fixed

    • Correctly implement the `AlazarGetWhoTriggeredBySystemID()` and `AlazarGetWhoTriggeredBySystemID()` API calls. Previous versions always returned 0.

    [4.3.1] - 2005-3-1

    Added

    • Initial release of Windows driver for ATS310.
    • Initial release of Windows driver for ATS330.

    Fixed

    • `AlazarGetWhoTriggered()` API routine that returns which channel or combination of channels caused the trigger to occur. This is useful in multi-channel transient recording applications. Note that this new API routine will only work with ATS850 hardware version 1.3 or higher.

    [4.2.1] - 2005-2-1

    Added

    • Support Master/Slave operation of up to eight (8) ATS850 PCI digitizer irrespective of the PCI bus scanning direction. Previous versions worked in motherboards that scanned left-to-right (when facing the BNC connectors), but not the other way around.

    [4.2.0] - 2005-1-1

    Added

    • Support for ATS850 v1.3. Older hardware versions are also supported. Users who have written software for the older hardware versions do not need to change their software when upgrading to the new driver.
    • Support Master/Slave operation of two (2) ATS850 digitizers.
