Hi everyone, I am looking for an EMC lab, preferably but not necessarily in California, with capabilities to generate calibrated field strengths (per EN61000-4-3) up to at least 20 V/m (before AM is turned on), with sufficient power generating and handling capability to run the below-described test.
In addition, I would like the chamber to be relative large, NOT one of the "compact-size" chambers. Ideally, it should be a chamber large enough to run a "10-m" or "5-m" emission test. The antenna distance for this RS test should not be closer than 3m. I am trying to quantify the relative improvement of a product that marginally failed (before modification) the EN61000-4-3 level of 10 V/m, in the frequency range 80-150 MHz, using an anechoic chamber and NEBS cable-rack with 24 long cables looped back between 48-ports of the DUT. I want to measure the threshold of susceptibility vs. frequency between 80MHz and 150 MHz before and after the modification. I am not interested in pass/fail criterion only. Therefore I need to be confident that the field is known at all levels, up to the maximum used/generated field strength. This implies that either the field generating system is proven to be linear up to the highest field strength (e.g. 6dB increase on power generator doubles the field strength at any levels), or that multiple calibrations have been performed at different, sufficiently closely spaced field-strength levels, so that I can interpolate between the calibrated levels. Does anyone have a suggestion which lab to use? Thank you, Neven This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
