The 11664A Detector must be used in conjunction with the HP Model 8755C Swept Amplitude Analyzer. The 11664A detects RF signal levels from -50 to +10dBm in the frequency range from 10 MHz to 18 GHz. Use of three 11664A Detectors enables simulaneous (amplitude only) transmission and reflection measurements via the 8755C Analyzer/180-series Display.

The 11664A Dector and the input stages of the 8755C comprise and ac-coupled systems. The detection scheme requires 27.8 kHz squarewave modulation of the RF input signal. Additional information is provided in the following section.
