The Keysight 11664A (formerly Agilent Technologies/HP) 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.
Keysight 11664A Detector units were previously manufactured by Agilent Technologies.
