EMI Results - Average Detector

Some of the recorded spikes exceed this test's limits. As a result, the HPT650M fails. Fortunately, at higher frequencies, conducted EMI emissions are low.

A couple of spikes at higher frequencies stand out in our chart. They remain under this test's maximum tolerance, though.
