The HP 11664E detector consists of a single Schottky diode housed in a metal frame with an APC 3.5 connector.
RF signal levels (dependent upon scalar network analyzer used) from -60 to + 16 dBm in the frequency range of 10 MHz to 26.5 GHz can be detected.
The HP 11664E detector rsquires the use of either an HP 8755C, 8756A, 8757 series scalar network analyzer (recommended equipment).
The use of three HP 11664E detectors, or two detectors and a bridge, enables simultaneous (amplitude only) transmission
and reflection measurements via the analyzer CRT. The supplied cable markers are used for identification when more than one detector is wed in a test setup. The HP 11664E Detector and the input stages of the HP 8755C/8756A/8757 comprise an ACcoupled system. This detection scheme requires a 27.8 kHz squarewave amplitude modulation of the RF input signal.
