I have BS EN61326:1998 which references IEC 61000-4-3:1995 which I believe has no test method above 1.0 GHz. I don't actually have the 1995 version to verify this. I have the IEC 61000-4-3:1998 which does describe test methods from 1.4 to 2.4 GHz.
Therefore, for BS EN61326:1998, there are no requirements to test above 1.0 GHz. However I do it anyways (at 10V/m with 80% AM modulation). I have seen real world interference problems from transmitters above 1.0 GHz. I also perform the 900 MHz pulse modulation test at 10V/m - although I have never see a problem with this. regards, Chris Poore -----Original Message----- From: [email protected] [mailto:[email protected]]On Behalf Of Gordon,Ian Sent: Friday, September 27, 2002 5:47 AM To: 'IEEE EMC & SAFETY PSTC' Subject: RADIATED IMMUNITY TESTING ABOVE 1GHz Everybody Does anyone know whether it is necessary to perform radiated immunity tests above 1GHz when applying BS EN61326 which is the product standard titled "Electrical equipment for measurement, control and laboratory use - EMC requirements"? The products concerned are not telecom or IT devices. The standard refers to IEC 61000-4-3 for this testing which includes tests above 1GHz at various mobile telephone frequencies. I believe the generic standard EN61000-6-2 refers to testing using pulsed modulation at 900MHz only.
