Well, it seems an Agilent/Keysight N9020A-503 MXA spectrum analyzer will find the way to me. Unfortunately it seems to come with the basic config, so I wonder if anyone managed to hack any of these or any other X-series spectrum analyzer. Of course my main interest is to enable the N9020A-EDP, N9060A series spectrum analysis extension, N9063A analog demod, N9064A digital demod, N9068A phase noise meansurement, N9069A noise figure meansurement, N9051A pulse meansurement and N6141A EMI test, but getting some of the other options would be nice, too.
Any ideas?
