Hello,
My PXI-4130 just came back from calibration and now my Channel 1 does not provide any output.
The PXI-4130 is running inside of a PXIe-8108 embedded controller and when I use the NI soft panel to control this card, Channel 0 works normally, but Channel 1 only puts out about -131 mV, regardless of the input setting. All of the indicator LEDs on the front of the PXI-4130 are green and it passes the self test, so this is a mystery. Further, I swapped in a spare PXI-4130 and that works fine, so it's not my controller that's screwing up. I also placed the offending PXI-4130 into a spare controller and it did not work there either, so all signs point to the card not operating correctly.
There doesn't seem to be any sign of physical damage to the PXI-4130 card, so is it possible that the calibration house somehow disabled the Channel 1 output? This seems really unlikely to me. Of course, the data that they sent with the card said that it was working flawlessly when it arrived and left their custody, so the finger will be pointed at the shipping company.
Does anyone have any advice?
