Re: [PSES] pre-compliance spectrum analyzer

Dunno, perhaps you might want to look at this stuff: http://value.rohde-schwarz.com/vi/value/emc-precompliance.html Keysight nee Agilent nee HP is recommending the N9000ACXA for pre-comp; and have seen on ebay for under $14k USD. Am an EMC amateur, and do very little pure EMC work, but prefer

[PSES] Best antenna for IEC 61000-4-3

I'm looking for suggestions on the best antenna to use for Radiated Immunity test according to IEC 61000-4-3 between 80Mhz and 1Ghz. (we use a dual ridge horn above 1Ghz). Our goal is to find an antenna which is not too large, yet, will give us good gain at the low end so we can generate

Re: [PSES] Best antenna for IEC 61000-4-3

Many years ago I used a 3109XP for testing powered wheelchairs, needed 30 V/m down to 26 MHz. This antenna worked well up to 80/100 MHz or so, and does even better in a small chamber where the tips couple strongly to the walls (the antenna current increases and the impedances are such that the

Re: [PSES] pre-compliance spectrum analyzer

Since a spectrum analyzer front end is usually wide open for the entire bandwidth, a signal out of the range you are looking at could be overloading the analyzer causing incorrect readings for the signals yor are looking at. Having a tuned front end is one of the advantages of an EMC receiver.

Just move the antenna in to a 1m test distance! :-) ___ I'm here to help you succeed! Feel free to call or email with any questions related to EMC or EMI troubleshooting - at no obligation. I'm always happy to help! Kenneth Wyatt Wyatt Technical Services LLC 56 Aspen Dr.

Re: [PSES] Best antenna for IEC 61000-4-3

How about having an Amateur Radio Operator design an antenna optimized for the lower frequencies? Or design one, one's self. Then calibrate it against a known antenna. Should not be difficult. Doug University of Oxford Department for Continuing Education Oxford, Oxfordshire, United Kingdom

Re: [PSES] Best antenna for IEC 61000-4-3

ETS/Lindgren shows two biconicals they claim will do 10 V/m with the headroom required for 80% AM with 100 Watts input: the 3109, and the 3109XP. Not plugging ETS/Lindgren, just giving examples. I think part of the problem with hybrid biconical-logperiodics is that the antenna is very deep, so

Re: [PSES] pre-compliance spectrum analyzer

There was a time when Doug's point was very important. I think that time has passed, for a couple of reasons. 1. Most testing is done indoors, so strong ambients are rare. If testing outdoors however, his point is extremely important, except for: 2. Pre-selectors are not what they once were.

At my workplace, we've got one of these: https://www.rohde-schwarz.com/product/esrp-productstartpage_63493-35077.html and it's pretty nice. Especially its huge dictionary of GPIB remote-control commands, which makes interfacing with LabVIEW convenient. R makes good products. However, I have

Re: [PSES] pre-compliance spectrum analyzer

http://www.ieee.li/pdf/essay/receiver_v_sa.pdf I just noticed you linked to a spectrum analyzer, yet I was talking as if we were discussing EMI receivers. There are several key differences even though I would have thought they were practically the same thing had I not done some research. I
