differential and RSE different results with labview

differential and RSE different results with labview

differential and RSE different results with labview

Using a function generator I made a signal with ground and signal to test a program. The program worked fine. But I found that labview reads a different signal for RSE (signal att. to ai0 and ground) and differential (ai0 and ai8).
The signals show a sin wave but the differential sin wave seems to be interrupted every 1/12period or so.

Can anybody explain this??


RE: differential and RSE different results with labview

That is odd-

What model DAQ card are you using?

Are you reading any other inputs along with this one?

Have you tried bias resistors on ai0 and ai8 to AIGnd?

RE: differential and RSE different results with labview


Did you set up the input configuration (RSE, DIFF) of the channel in your vi to match your wiring scheme?
