Have the evaluation performed at both 3 meters and 10 meters. Should be interesting to see the results.

The purpose is to test both, the facility (semi-anechoic v/s OATS) and the quality of results. The comb generator is my first approach. A standard test sample(with cables) will follow. Any procedures, data, results, experience.... on this issue ? -----Original Message----- From: Ken Javor [mailto:[email protected]] Sent: Monday, 7 January 2002 13:47 To: Rao, Praveen; [email protected] Subject: Re: Comparing EMI test results Whether a comb generator is a good artifact depends somewhat on what your purpose is. If your purpose is to check how well calibrated the site is I think a comb generator is an excellent artifact because it is physically small and should generate the same radiation pattern at all facilities. But if your purpose is to check the "quality" of the testing done at different facilities including how good the test personnel are, then I believe you need a device with attached cables, since maximizing emissions will then involve not only height searches, but also rotation of the turntable and movement of the attached cables. Maybe you can attach a cable or two to the rf jack that normally seats the stub. on 1/6/02 8:16 PM, Rao, Praveen at [email protected] wrote: > > > > I'm trying to setup a programme to compare test results (for > Radiated Emissions) between test labs.
