The HP Model 11664A Detector must be used in conjunction with the HP Model 8755C Swept Amplitude Analyzer. The 11664A detects RF signal levels from -5G to +10 dBm in the frequency range from 10 MHz to 18 GHz. Use of three 11664A Detectors enables simultaneous (amplitude only) transmission and reflection measurement via the 8755C Analyzer/ 180-series Display.
The 11664A Detector and the unput stages of the 8755C comprise an ac-coupled system. This detection scheme requires 27.8 kHz squarewave modulation of the RF input signal.
