PCI-6025E analog output

[Andre M Zelak]

I´m trying to use a Analog Output from a PCI-6025E board, but I had some problems. In MAX program test panel I update the channel 0 with 0V, and I measure -3,9V in the output pins.

I believe that this is a problem of calibration. I tried to calibrate, but self E-Series Calibration vi doesn´t work.

Have someone ever had this problem?

Thanks,

[eh]

Just some things to check.
Are you using the AO gnd as your ground reference? Does the voltage change from -3.9 to 0 if you set it to 3.9?
Are you using the analog inputs to measure it?
If so are they set to NRE and the ground references tied together?

I'm using the AOGND as groud reference.
If I set the output to +3,9V, it represent to aprox.
-2V. Just if I set +6,3V to the output the voltage change to 0.

I'm not using the analog inputs to measure it.

Do you believe that is a problem of calibration?

Thanks for all,

André
