EMC noise in instrumentation amplifier.
EMC noise in instrumentation amplifier.
(OP)
Hello,
First thread on this forum! Thank you for giving me you're opinion about a question that I have.
I am using a data acquisition system (ADInstruments Powerlab 16/30) to record muscular activity from electrodes. So far, everything is working properly.
I recently got an approval to move my setup into a new lab. However, it's situated right next to the main electrical room of the hospital I am working for.
My question is: Do I have to worry about the EMC noise? Is there a danger for my data's integrity?
Thank you very much!
Jonathan

RE: EMC noise in instrumentation amplifier.
Yes, always.
Maybe, depending on how well you shielded everything, and depending on what the environment in the new lab looks like. Until you do something, it's unknown territory. There may be other things completely unrelated to your concerns that will actually bite you.

RE: EMC noise in instrumentation amplifier.
Thank you for your quick answer.
Other than check if everything is properly shielded, is there anything I can do before to make the big move? Is there anything in particular I have to look at? (in the electrical room for example)

You could also take some electromagnetic field measurements.

One thing you could do is to have measurements of conducted and emitted EMI carried out. If the levels are above accepted in your country, then demand that something is done about it.

You should also compare the mains and grounding in the new lab, relative to the old lab.
