Mark, for the most part I always had 6 of the highest measured in each polarization, for a total of 12. Depending on what we saw, we may have measured more for curiosity's sake.

Hello PSES brain trust, When doing radiated emissions measurements, how many frequencies should be quasi-peaked? CISPR 16-2-3 clause 6.4.9 states: "Of those disturbances above (L-20dB), where L is the limit level in logarithmic units, the disturbance levels and the frequencies of at least the six highest disturbances shall be recorded." We have always done QP measurements on all peak measurements above the limit, even if that is more than six points. I have a lab arguing that they only need to measure the top six, regardless of how many peak measurements are above the limit. Any thoughts are appreciated.
