Want to get 80 voltage signals( about 2 mV). Is PCI-6255 a good choice?

Hi,

I want to get 80 voltage signals from the surface of hearts, the signals voltage amplitude are about 1~2 mV. Is PCI-6255 a good choice?

Thanks

Hi,

Welcome to the National Instruments forum! It depends whether you are using reference single ended or differential measurements. Single ended you would be able to take 80 measurements but each diffential measurement takes up two channels. There should be no problems with the resolution/accuracy of the measurement.

Cheers,
