[Noisy Data from USB-231 Differential DAQ]

That is the case for the software paced mode right? Can I use the hardware paced mode to scan two channels at the same time? If yes how can I do it?

Understood, Thank you.
One more question please. Are the analog input channels synchronized? Will the data acquisition start at the same time for all channels or there is a delay between them?

I was sampling just one channel using a voltage generator. I was using InstaCal and doing an analog test. When looking at the data I was noticing a 0.02V error for the differential DAQ and 0.04V for the single ended one based on the value set for the voltage generator.

Thank you for helping.

I checked the input offset and indeed, I was getting 0.

I also checked for the ground loop, but I was getting the same offset so there is no ground loop.

I was using before the USB-205 single-ended DAQ and the offset was 0.04V so I moved to a differential DAQ in order to reduce this offset and it got reduced to 0.02V. Is there anything else I can do to get rid of this noise? I thought that changing the DAQ to a differential model will reduce the noisy in a more significant way.

Hello,

When I set my voltage generator to 0V and I connect it to the analog input pins of the DAQ, I get 0.02V. I was using my code to acquire the analog data and also InstaCal and with both I get noisy data. Is there a solution to this problem?  

 

Thank you.
