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. Bob R.

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 From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, February 14, 2011 3:15 PM To: [email protected] Subject: Considering a consultant to help with semi-anechoic chamber 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 [email protected]. I would prefer somebody at least somewhat local - we are in the Vancouver BC area.
