EMI Filter and Quasi-Peak Detector

EMI-DSA800 option provides Quasi-Peak detector and EMI filter (200 Hz, 9 kHz, 120

kHz, -6 dB bandwidth). Quasi-Peak detection is a weighted form of peak detection.

For each data point, the detector detects the peaks within the specified time interval,

weights the peaks detected using circuit with specified charge and discharge

structures as well as the display time constant specified in the CISPR Publication 16

standards and display the result. By default, the instrument uses Gauss filter and will

switch to EMI filter automatically if Quasi-Peak detector is selected.

Press BW/Det at the front panel. Then, press Det Type to select Quasi-Peak

detector. At this point, the instrument automatically changes the filter type to EMI

and the Filter Type menu is grayed out and disabled. EMI-DSA800 option is used in

electromagnetic interference test.
