I've had three radiocommunications test sets that I've used extensively.
The first is a Marconi 2955A which is getting a bit long in the tooth now and has no spec an. But it is excellent for getting most other jobs done, the UI is easy to use after a couple of minutes of familiarisation. Probably the easiest I have to use, mainly because there's no cellular nonsense getting in the way. The one I have has a 75W power capability, I'm not sure if that's standard or not. It'll demodulate AM and FM through an internal speaker. Limited to 1GHz. I had to fix the power transistor on the CRT line output transformer once. Quick boot time.
The second I use is an Anritsu MT8802A with option 7, the spec an. The UI is a PITA because it's designed primarily for cellular use. It has limited power protection (10W), I managed to bust the attenuator in one because of that. I couldn't figure out how to replace the attenuator, the fasteners wouldn't budge. I ended up buying another one. There is no speaker, but it works up to 3GHz including the spec an. The screens go dim, I found that after re-capping the entire unit, my screen suddenly was much brighter. Put aside at least a day to re-cap one of these. Very slow to boot.
The third unit is an Agilent 8935 E6380A. While it's mainly designed for cellular use, you can tailor the unit to power up in a pre-configured mode, and you can store a number of tailored modes on the device itself that you can easily recall. Mine had a power supply fault when it arrived so from memory it looked like it worked but when you hooked anything up to it nothing happened. It turned out to be an easy fix (love those!) a simple LM317 replacement which I had in stock. It operates up to 1GHz plus some random cellular bands above that. It has a tracking generator as well as the spec an. There is a speaker, and composite video out. 75W power continuous. Medium slow to boot.
My use case is 99% final test in production, 1% listening to FM radio ;-)
