USB-ME64 input impedance

Post  holly87 on Sun Jul 01, 2012 10:01 pm

Hi!
I have a question about USB-ME64 input impedance. I see that imput impedance for the 60 analog signals coming from the filter amplifier is 10 kOhm. On the other hand, the imput impedance for the additional 4 analog inputs is much higher. Could you explain me why??
Many thanks!

Dear Giulia,

I checked that information with our engineers. It seems you spotted a mistake in our datasheets. The input impedance for all channels is 10kOhm. This applies to analog inputs as well as electrode data channels.

I already notified my colleagues to update the datasheets.

Thank you for your help in this issue.

Thomas
