HP / Keysight / Agilent 85650A Overview
The 85650A quasi-peak adapter works with the HP 8566B, 8567A, and 8568B spectrum analyzers and with the 85685A RF preselector to complete an EMI test receiver system. The quasi-peak adapter adds the special bandwidth filters and quasi-peak detection capability. These bandwidth filters (200 Hz, 9 kHz, and 120 kHz) may be selected using either peak, quasi-peak, or average detection.
