2001 - From NSA to Site-Reference Method for EMC Test Site Validation

Wolfgang Müllner, Heinrich Garn 2001 IEEE EMC International Symposium, August 13-17, 2001, Montreal, Canada

Electromagnetic compatibility compliance testing of electronic apparatus includes the measurement of radiatedemissions in the frequency range of 30 MHz to 1 GHz. To achieve equivalent test results from different testing laboratories, test sites must be of validated, standard performance. This paper suggests a substantial improvement to the standard site validation procedure: A new "sitereference method" for site validation is suggested. It avoids the determination of the antenna factors of transmit and receive antenna, gives full traceability and thus minimizes uncertainties in the measurement result. This improves the reliability of judgements upon site performance and helps to economize the design of test facilities, e. g. anechoic chambers.
