Hi,
Can someone tell me how to implement AC coupling function using Red Pitaya board?
Can i just simply series a capacitance(0.1uF) into the RF input?
Thanks in advance.

I think that should be fine. Make sure the impedance of your cap is very low at your lowest frequency of measurement or you will phase shift and attenuate your lowest frequencies.

This method involves the usage of internet to promote the products and services
of companies at much lesser costs.

To series a capacitance(0.1uF) into the RF input should be alright.
