pxie 6363 differential analog input problem

[Vang25]

Hi all,

I have a pxie 6363 DAQ card that is giving me unstable analog input measurements in differential, NRSE and RSE mode. This is happening with all the channels. Self test and self calibration test all came back with a pass. With no source connected to the input, it will ramp up and down. With the input terminated to AI GND,  the output will at time will stay at +10.6V, - 10.6V or +3.6V. I'm not sure what is going on with this card. I have another exact card within another chasis and it's fine. Any help with this is appreciated.

Thanks,

Vang

Hi,

I'd like to ask you wich version of DAQmx are working with? 9.5 isthe latest version.

Also, can you please download the DAQ Diagnostic Tool and run a test for your card.
