Problem:
I cannot install the ATS850 driver in my
PC. I am using Windows XP.
Solution:
It seems like you do not have installation
rights on your PC. Please log in to
Windows XP as an Administrator or as a user with
installation rights and you will be able to
install the driver without any problems.
Please note that all AlazarTech drivers are
fully compatible with Windows XP, Windows 2000
and Windows 98SE, so there should be absolutely
no problem installing them.

Problem:
I inserted the ATS850 card into my computer and
clicked on the Have Disk button, but the
operating system reports that the disk has no
information about my hardware.
Solution:
There can be the following reasons for this
behavior.
1. Your installation disk is corrupt.
Please download a fresh copy of the driver disk
and try again.
2. You did not insert the floppy disk or CD into
its drive before asking the operating system to
install the driver. Please insert the disk
and try again.
3. The path you specified after clicking on the
Have Disk button did not match with the path
where the installation disk was. Please
specify the correct path and try again.

Problem:
I installed my ATS850 in my PC. I see that
there are four LEDs that are always lit, whereas
the others go on and off as I operate the
device. Is this normal?
Solution:
Yes, this is perfectly normal. The four
LEDs that are always on signify that four of the
most important parts of the circuit are working
properly. The three other LEDs show the
status of BUSY, TRIGGERED, and PCI ACCESS flags.
They tend to go on and off depending on how you
exercise the card through software.

Problem:
We injected a 10 KHz, 1V sine wave into the
ATS850 using API Panel software. We
selected 50W
impedance and AC coupling. Software
displayed a sine wave of only 300 mV amplitude.
This does not seem right. Is my hardware
defective?
Solution:
Your hardware is functioning exactly as it
should. Note that the lower cut-off
frequency in AC coupled mode when you have 50W
impedance is 100 KHz. This means that any
signal lower than approximately 150 KHz will be
attenuated (even 100 KHz signals will be
attenuated by about 30%). Since your
signal is only 10 KHz, it will be attenuated
much more.
To measure your signal using AC coupling, set
input impedance to be 1 MW.
The lower cut-off frequency in AC coupled mode
when you have 1 MW
impedance is 10 Hz.
