Sine wave voltage too low on PXI-6031E

[joeljkp]

I have a PXI-6031E on which I'm generating a sine wave on output channel 0 through MAX's test panel. I have a SCB-100 breakout box in which I've connected pin 20 (DAC0OUT) to pin 5 (ACH1). Again in MAX, I'm plotting the readings from input channel 1 to see if I can see the sine wave.

The wave appears, but the mean voltage is too low, pushing the waveform against the bottom edge of my voltage limits. See the attached screenshots for details.

How do I "shift" the waveform up in voltage?

Hi Joel

Which measurement mode have you selected for the board? Differential, RSE or NRSE. Dependent on the mode you've selected, the wiring is different. Please check the User Manual of your board for more details.

Hope this helps,
Luca

I have my SCB-100 set to differential mode. I just changed that to RSE, and it's better. The actual midpoint of the wave still seems to be somewhat random, but perhaps that's normal?
