Re: Spectrum Analyser TR4172
Those feature docs you mention would be very handy. I often use the KE5FX HPIB stuff, including the 7470A emulator; that's how I grabbed those 8753 plots. I also use his phase noise measurement tool with the 4172 and it works nicely. Being able to produce plots from it would be very nice as well, and I actually do have a genuine HP7550B that you don't want to get your fingers to close to if it's plotting... capable of at least 1,000 paper cuts per second.
Having a suitable dipole and being able to read uV/m would be handy in my field of work. It seems that I remember being able to use 7Hz by just inputting it directly though - perhaps that's a change they did in later firmwares? And I think the data for the smith chart is missing with mine - I seem to remember trying the key combo to get it in the past and it simply did nothing... likely due to not having the impedance option.
