Problème de stabilité et de précision de mesure de tension sous MAX

[jeanbat29]

Hello,

My goal: To acquire a voltage output by an LVDT.

While using a multimeter or an agilent I have a measuring accuracy of the order of 5mV.

Otherwise, using two different cards: PCI 6013 or 6014 + CB68LP terminal and different ways (test on two different PCs):

The MAX test panels give me an accuracy of the order of 100mV! Therefore impossible to obtain sufficient accuracy with the LVDT.

Big noise, but where does it from??
