This optional upgrade provides up to 120 MHz analog input on each of the four channels on the ATS9440. With software selectable attenuation, you can achieve an input voltage range of ±100 mV to ±4V.
Software selectable AC or DC coupling further increases the signal measurement capability. Low frequency cut-off for ac-coupled input is at approximately 100 KHz. It must be noted that input impedance of all channels is fixed at 50 Ohm.
