Manual

The 85650A quasi-peak adapter is an accessory used with the 8566B or 8568B spectrum analyzers for performing quasi-peak measurements as recommended by CISPR. These include the correct 6 dB bandwidths (200 Hz, 9 kHz, 120 kHz) and the specified detector charge and discharge time constants.

 

Specifications:

Frequency Band (MHz) Bandwidth at 6 dB Charge TC (ms) Discharge TC (ms)
0.01–0.15 200 Hz 45 500
0.15–30 9 kHz 1 160
30–1000 120 kHz 1 550
