2.3.1.7 Quasi-Peak
It is a weighted form of peak detector. For each data point, the detector detects the
peaks within the corresponding time interval. The peaks detected are weighted using
circuit with specified charge and discharge structures as well as the display time
constant specified in the CISPR Publication 16 standards and the result is displayed.
Quasi-Peak detector is applicable to EMI testing.
Note: compared to the discharge time, the charge time of Quasi-Peak detector is
much shorter and can reflect the amplitude as well as time distribution of the signal.
