I have been using InstaCal to assess a USB-1808X I have. I have the board configuration set with all CHI channels set to differential. The board test shows a square wave generated from DIO0 being received on CH0H (CH0L is connected to AGND) as a low amplitude (0.17 V). I have a scope probe across CH0H and L. It is showing a 0-5 V stable square wave. I have tried all of the CHI channels with the same results. Digital tests all pass, but I am not convinced the unit is working correctly. Any other tests I can do to test the viability of this unit? Is it possible to send this in Digilent for assessment/repair?
