Meeting Topic: “Aiding the 17025 Laboratory Accreditation Process by Capturing Key Performance Data on RF Power Amplifiers”

ABSTRACT: The technical case can be made that there is no need for periodic calibration of the RF power amplifier in a RF immunity system. This is because the new IEC61000-4-3 Edition 3 stipulates checks on amplifier harmonic and compression levels at all test frequencies, and if met, the immunity system is deemed compliant. However, this leaves the situation where the most expensive piece of test equipment in the set up has no dedicated calibration type data on file. This presentation describes and explains the more baffling amplifier performance metrics, and provides guidance on a simple way of capturing the metrics using test instruments available at most test laboratories. The captured data can then be presented during the 17025 audit under the trend analysis methodology.
