line noise enter despite low impedance.

Post by vattha »

Hi All,

What I understood is that I should get the offset to be between +-20 mV to have a good quality signal. But I observed differently: see cp2, p2, and po4 in the attached figure. All three locations have stable offsets within the range but the corresponding signals are bad. Could somebody please suggest me for possible reasons? and how can I prevent it in the future? Thank you in advance :)

Best,
Attha

Gel bridge with DRL, also see viewtopic.php?f=7&t=810&p=3048 . Use just enough gel to fill the holder, but not more.
