Hi Dave,
one nice feature is that some reasonably priced analyzers offer 1Hz
resolution bandwidths (8560E etc) which is really nice for precise work at very
high frequencies... and for precise phase noise work which is usually
calibrated in dBc per 1 Hertz.
It allows one to clearly see 50/60Hz power supply noise for example at
Microwave frequencies which would be hard to differentiate with a 30Hz RB.
I always miss that feature in lesser units such as the 8591A series.
bye,
Said

And yet another feature modern analyzers have is digital display
memory - which makes it usefully possible to make slow narrow band
measurements with say 100 Hz or 30 Hz bandwidths. Really antique
analyzers had display storage tubes or similar arrangements as options,
but all even slightly modern ones have fully integrated digital storage
and displays.
