My goal: To acquire a voltage output by an LVDT.
The meter or using an agilent I have a measuring accuracy of the order of 5mV.
By cons, using two different cards: PCI 6013 or 6014 + CB68LP terminal and different ways (test on two different PCs):
The MAX test panels do not give me that accuracy of the order of 100mV! Therefore impossible to obtain sufficient accuracy with the LVDT.
Big noise, but where does it from??

And thank you for posting here.
Could you explain more your configuration?
What is your input configuration (NRSE, DIFF, GRSE) ?
You can take a look on this link :

Thanks for your answer.
The Mode is : On demand
Input Configuration: Differential
I had a look to the group loops and returns but... with a simple multimeter I have a good accuracy at the wire at the output of the signal, with MAX...no!
