Hallo, I'm posting here because it sounds the best place for this topic after all.
My problem is the synchronization of two FFT analyzer (either 35670 or 3563, we have two of both) where one is primary and the other is secondary, so that I can sweep the primary and read voltages and currents here and there and calculate at once different transfer functions in parallel (e.g. input impedance and forward gain).
I've seen some connectors labeled REF IN and EXT SAMPLE IN, but it is not clear if they may be of help and how.
thanks for your attention
