Re: Considering a consultant to help with semi-anechoic chamber relocation and performance improvements
hi Bob, wish I had your patience and Money :-) Or maybe you have mine lol... I guess you're in one camp or the other, I'll stick to Agilent. I could never get used to reverse polish logic either, despite being told how much better it was As for a click receiver, check out the PMM, I have, it's a 3rd the cost of R and S, and every bit as good Make that better cos' I'm not worrying about the $8k repair bill for the RS every time I hook something up.

RE: Considering a consultant to help with semi-anechoic chamber relocation and performance improvements
Chris, Of the analyzers I have used, I like the RS 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.

RE: Considering a consultant to help with semi-anechoic chamber relocation and performance improvements
I like the 7405a EMC SA to 26.5 GHz. We have a compact 3m. I've added cones and tiles to make a semi FAC. While the NSA is just about in, it is somewhat different than the OATS we have. How do you do a NSA without the 4m scan? Think out of the box! It is still not valid, but for engineer work, it is close enough. Note, when re-assembling the chamber, be sure to clean the edges of the panels where the electrical contact is to be made. Some Cu tape and Cu wool will be very useful too. How to know? Many years ago, I ran across an old piece of equipment for testing seams such as these. It applied an AC current via a couple of connections, one each for the far diagonal corners. Then had a battery powered magnetic pickup from what I could tell, and an analog meter reading, like an S-meter. Get that pickup near an amonaly in the field and the meter would swing. Loose hats and flats (that the joints between panels) would swing the meter a lot. clean the joint and tighten, meter would settle down. Attitude is Mind over Matter. If you don't Mind, it doesn't Matter...
