DAQmx problem for acquisition

[Beutlich]

hi mahasan,

Testing on a different channel is a good idea. I am curious if you get any bias when shorting AI+ and AI-. Also, I am curious about the function generator. Is it battery powered or does it plug into the wall? Do you have a single BNC connected directly between the 9215 and the function generator or are all of these instruments attached at once through BNC splitters?

Hi all

Thank you all again for keeping your kind concern.

Yes, I have tried all analog input channel for acquisition 😞

But, still the same problem.

You know, I found in the Oscilloscope the peak-peak voltage is around 6V, Frequency around 60 Hz but, in the LabView the signal is getting different.

I have attahced all four channel output for your reference in my two post

Hi all,

Thank you so much.

I have attached here my 4th channel output here and Oscilloscope output again.

I am using plug into the wall function generator.

And, The BNC 9215 is directly connected to the function generator.

Thank you again all for helping me to resolve this problem.

Looking forward to hear a solution

Regards,

Hi Mahasan,

Could you wire the center conductor of the BNC to the sheilding of the BNC on one of the ports and see what data you get? It should be 0 (since you are measuring a short), so if you get anything else than the device may be damaged. If that works, what happens when you try to measure a simple battery like a AAA or 9V or something?
