Van: [email protected] [mailto:[email protected]] Namens Brent G DeWitt Verzonden: Wednesday, September 28, 2011 1:21 AM Aan: 'Kunde, Brian'; [email protected] Onderwerp: RE: [PSES] BS EN61000-4-3 and calibrated fields. We have done this at several labs I work for, but it was always just a sanity check to make sure that neither the amplifier nor cables to the antenna had failed. It is totally useless as a function for leveling for commercial immunity measurements. Best regards Brent From: Kunde, Brian [mailto:[email protected]] Sent: Tuesday, September 27, 2011 8:19 PM To: [email protected] Subject: Re: [PSES] BS EN61000-4-3 and calibrated fields. Not to hijack this thread, but why do some test labs setup the Field Probe in the chamber next to the EUT during the test? The measurement with the EUT in the field should be all over the place and would have little value. Am I missing something or are some labs leveling off the Field Probe during testing? From: [email protected] [mailto:[email protected]] On Behalf Of Ian White (UK) Sent: Tuesday, September 27, 2011 6:00 AM To: IEEE Forum ([email protected]) Subject: BS EN61000-4-3 and calibrated fields. Could you please help: Could you explain what is the correct procedure when using an anechoic chamber which is calibrated and operating to EN61000-4-3. During calibration of the chamber, a calibration file is made and it is assessed according to the guidelines laid down under BS EN61000-4-3. During calibration the chamber is empty. During a normal test run a UUT is put into the chamber. The questions is : a) Do you use the calibration file as the starting point and adjust the field strength which may have changed due to the UUT being in the chamber. b) Just take the calibration file and run it and except the filed strengths would have changed due to the UUT being in the chamber.
