Quasi-peak detector specifications
The EMC analyzer displays the quasi-peak amplitude of a pulse
radio frequency on continuous wave signals. Amplitude response
conforms with Publication 16 of Comite International Special des
Perturbations Radioelectrique (CISPR) Section 1, Clause 2, as
indicated in the relative quasi-peak response table.
