NI USB 6363 signals drift (differential configuration)

[Aleksi-]

Hi!

I just changed a data aquisition task of 2 signals from "RSE" to "differential". After this the signals started to drift really bad. Could this happen because I haven't yet hooked up the DAQ to the actual voltage source? Also this loop is simultanously sending output signals to the DAQ outputs. I am just pretesting the configuration.

Thank you in advance.

Yes.

If you want you can connect the +5v from the board to the channels if you want an actual signal.  But without anything hooked up the voltage can wander around.

Worked like a charm. Thank you!
