NI-6009 200 Hz noise

[MichiVentu]

Hi!

I am using a NI-6009 and I am experiencing a 200 Hz noise in the environment. I read an old post when someone was experiencing something similar with a NI-6501. But the content of the post was removed. Any idea on how I can solve the problem? 

Thanks,

Michela

Can you elaborate on the characteristics of the noise ? Are you sampling at least at Nyquist ? If you are sampling too slow, the noise may be aliasing

Can you also elaborate a little bit on your set-up?

What kind of cabling are you using? What is the general environment of the measurement.

The 6009 on itself doesn't produce the 200Hz noise, so it needs to be something in your environment which is inducing it.

You aim should be to improve the wiring/signal conditioning in front of the 6009 and then adjust the sampling rate of the card to take care of any anti-aliasing as mentioned by Taranjeet.
