NI SweptSine.vi produces Error -200077 when in differential mode vs RSE?

[josh100482]

Hi,

I am using the labview Sound + Vibration Toolkit's SweptSineFRF(DAQmx)_SoundAndVibe.vi and trying to measure response from two devices using the differential mode on the DAQ Configuration tab.  Everything works fine when using the RSE terminal configuration but when I switch to differential the program gives me an Error -200077 and says the initalization program fails.  Any reasons to why this happens?

Thanks,

Josh

Hi Josh,

What is the hardware you use?

This sounds like hardware doesn't support such a terminal configuration.

Please also define whether it causes from AO or AI?

Sorry, I solved my problem.  I didn't realize that the program cannot output as a differential signal.  When I changed this feature to RSE everything worked as usual.  Thank you for your reply.
