Chris,
Of the analyzers I have used, I like the R&S ESI the most. Expensive, though.
It took me a while to warm up to it, it was a lot different than any of the
HP/Agilents that I have used (859x, 8566, 740x). The 740x is also nice
analyzer. I use that to perform the conducted immunity level setting procedure
since it is faster than anything else I have used. I can do a 150k to 230M
calibration in less than 15 minutes with it.
We have recently contracted with Panashield to come in and handle the 1 - 6 GHz
setup. We looked into buying the necessary equipment and learning how to use
it, and how to perform the verification, and decided to let them handle it.

Good luck Jim… We moved one two years ago and that pain is still fresh
in my mind. The only advice I can offer on that is to label everything and
take plenty of notes/pictures.
While I won’t be moving a chamber anytime soon, we are trying to get
approval to replace the same, aging 856x stack. If anyone cares to comment on
that online, I would be interested in any thoughts or recommendations as well.
We’re also in the same situation of needing to go beyond 1GHz RE measurements
(also in a 3m SAC), so any comments on that topic would be appreciated as well.
Thanks,
Chris

relocation and performance improvements
Hi everyone: We are about to move (groan) and while this generally is
a pain, it provides the opportunity to fix a few problems along the way. Our
3m SAC is usable, and indeed gets fairly heavy use, but is not as good as I
think it could be, in a few ways:
- Our emissions measurement correlation to "real" labs is OK but
could be better, particularly on conducted emissions
- Our aging HP rack (the classic 856x series) is getting old and
is starting to be costly to maintain - time to switch?
- We have always just had a manual turntable and would like to
see what's involved in going with a motorized turntable and controller
- We have aging cones, many with broken tips - maybe not an
issue, but maybe it is?
- We haven't researched what it would take to go past 1GHz with
our RE measurements, but we need to
- Etc.
I think it would be worthwhile to have someone who is an expert in
design and troubleshooting of SAC's and EMC instrumentation come here, give us
a once-over, make recommendations for improvements that we could implement as
part of the move, and perhaps participate in the teardown and relocation of the
chamber (not as simple as it sounds) or recommend someone who could.
If you are interested and qualified, or know someone who is, please
reply to me off-line at jim.eich...@ca.schneider-electric.com. I would prefer
somebody at least somewhat local - we are in the Vancouver BC area.
Thanks,
Jim
