capacitive coupling to AC couple a signal with "NI-PXIe-6124" DAQ device.

[af.ra]

Hi every body.

I need my input channel to be AC coupled but my device soes not support AC coupling and gives me the error when I try to do that using coupling property for analog input.

Does any body know how I can Ac couple my signal by inserting a capacitor in series with the signal? how can I decide about the capacitor size?

thank you.
