Wow,? $1400 for a calibration is outlandish. If you run all your
diagnostics, chances are your 8920 is working okay but may be off
frequency, etc.. If your doing commercial work requiring a cal,
you may need it. Just to let all know, the calibration on the 8920
units involve running the internal diagnostics then the "percal"
program to adjust the 8920 internal frequency standard, voltage
standard and audio levels and a few other minor things. Then the
power meter and DC offset are zeroed from the front panel. After
that, we run the performance evaluation. This checks most all of
the AM, FM, rf in/out levels, audio, power meter, receive and
generate and spectrum levels, spurious levels, etc. This is an
automated test that produces some 20 pages of performance data.
The performance evaluation insures that the 8920 is accurate and
tests much more than the internal diagnostic program. Sometimes,
the performance evaluation reveals faulty modules or hardware
failures that the diagnostics don't show. I hope this
helps....Rick

Fully agree even though I have not used Ricks services for
actual repairs or mods but only for advice as well as Rick's
excellent posts here in the group.
I just wish we would have a similar workshop here in Sweden (or
within Europe) that has the same experience and knowledge that
Rick and his Amtronix has.
I am located in Sweden so shipping my 8920A back and forth to
USA is just to expensive.
I would like to get my spectrum analyzer module calibrated and
Agilent in Sweden would charge me 1400 USD to calibrate my 8920A
(which would be a full calibration and not just the SA module).
It would also be nice to upgrade from 60W input module to the
high power option 100W.
