Most analyzers are not CISPR 16 compliant. Receivers are always easer to
read QP and Avg. directly. If you can pass the CISPR limits with a peak
reading (analyzer), you can most definitely pass th

Muriel,
Unless your spectrum analyzer is equipped with a tracking pre-selector, or a
high pass filter, you run the risk of high level emissions at frequencies
below 150 kHz desensitizing the front end. This will result in readings
that are lower than the actual levels. I remember seeing this a
