Hi, I need to run EMC tests on a piece of high-power medical equipment that is used on an intermittent basis. The run time is about 15 seconds to 2 minutes on-time, followed by about 10 minutes off-time. This is comparable to typical system usage. This causes problems with EMC testing, since you normally need a longer observation period.
1) The equipment could be operated continuously, but extra cooling would have to added to the test setup, which is not part of a typical system. In the spirit of regulatory intent would this be considered overtesting? 2) Could testing be done at the highest power level that allows continuous operation? What load conditions/test setup are appropriate for an application like this?
