As I am getting closer to retirement I have been thinking about
buying a used spectrum analyzer since I will not have access to
one at work. Unfortunately I am not familiar with all the
models from say 5 to 15 years ago. Is there a good reference
describing the different HP/Agilent, Tektronix, etc. models and
which are good and which to avoid. A quick look on Ebay shows
HP 4195A, 8561E, 8562A, 8562B, 8563E,8565A, 8568B,8569B, 8591E,
8593E, and 8594E. Similarly for Tektronix 492P, 494P, 495P,
495A, and 2755P. Is there some kind of a used buyers guide
available. I understand spectrum analyzers at a moderate level
and realize the differences between frequency range, external
mixers, dynamic range, bandwidth etc. but finding the specs in a
manner that makes them comparable is hard. Thanks for any advice.

My "rule of thumb" has always been.... HP for spectrum analyzers,
and Tektronix for Oscopes..... Fluke for Dvm's and Lambda for Power
Supplies.
