And the Marconi 2955,2965 & 2945 series family are all still in strong use.
(Marconi was first to market the radio test set in the form we recognise today)

The HP 8920A may be obsolete but it is still supported by Keysight in the UK (and USA)
Worth asking them for a price, it might not be as bad as you think, fully automated calibration is cost effective.
Calibration is no problem, repair is subject to parts availability.
Still lots of these in use. Analog radio isn't dead yet. Demand is strong enough that Keyight sell a 8920A "clone" the M8920A.
Basically a bunch of PXI modules and software. R&S still sell plenty of the CMU500 too.
