Has their been any discussion on adding a Quasi-Peak Detector (QPD) algorithm in addition to the averaging/min/max detection algorithms?
If so, would it likely go into the tinySA app?
? ?I worked in EMC for a number of years and don't remember there being a DSP algorithm for quasi-peak detection.? All our receivers used physical quasi-peak detectors.? That was a number of years ago and maybe the mathematics have advanced since then.
? Best strategy in lieu of not having a quasi-peak detector is to ensure all your emissions are below the peak limit.? The peak emissions should always be higher than the same emissions measured with a quasi-peak detector.? Of course that means that you may spend some time reducing emissions below the peak limit that already meet the quasi-peak limit, but its better than arriving at a test house and finding your device fails the quasi-peak limit.
