This is the sort of think you should discuss with test-houses, to get an agreement how to proceed under practical conditions. For example, if you use peak detection of RF instead of quasi-peak you can speed up the processes a lot, and then just investigate any 'hot spots' with the Q-P detector. It really is better to use normal operating conditions for testing rather than any substitute condition. -- OOO - Own Opinions Only.
