calculate difference between two signals.

[M_Shaban]

I have two transmitters each one emitting signal with the same parameter (same frequency and amplitude ) to second one .

so with two RFSA in the same chassis  , how can I calculate difference in phase and amplitude for two signals at the same frequency ????

What hardware are you working with and have you tried anything so far?

With two RFSA devices, have them share the same LO and then synchronize the acquisition. This should allow you to compare the data.
