tension mini sur module 9205

[titi2010]

Bonjour

une question sur un module compact daq 9205, je fais l'acquisition en tension d'un signal qui varie entre 0 et 50mV, la mesure se fait normalement avec un petit probleme.

la source de tension est stable ( par ex: 10mV) et lorsque je fais l'acquisition mon signal fluctue je dirai meme qu'elle est pertubée avec des pics de tension

est ce que mon module peut mesurer des tension aussi faible ? ou alors savez vous d'ou peut venir mon problème

merci

Hi,

And thank you for posting here. Please post in english on this english forum. If you want, you have a French community on this link:

Titi2010 want measure a voltage signal between 0 and 50 mV with DAQ9205. Nevertheless the signal is disturbed (noise and voltage peak).

His questions:

The DAQ9205 is able to measure low voltage?

Where does the problem from?

Could you give me more details about your configuration?

What is your input configuration (NRSE, DIFF, GRSE) ?

You can take a look on this link :

groud loops and returns

Did you specify your configuration in LabVIEW or MAX (NRSE, DIFF, GRSE)?

Did you use LabVIEW (DAQmx function or signal express) or MAX?

Do you know the range of your voltage peak?
