Agilent/Keysight 11664B

The Agilent/Keysight 11664B is a microwave detector engineered for scalar network analyzer systems, delivering envelope detection of RF signals modulated at 27.8 kHz. Purpose-built for the 8757, 8756, and 8755 series analyzers, this detector enables accurate microwave measurements across a broad frequency span. It operates with 50-ohm input impedance and interfaces via Type N male connector.

The unit handles dynamic range from +16 dBm to -60 dBm, with maximum input power rated at +20 dBm (100 mW). Operating temperature range spans 0° to 55°C, with storage capability from -40° to 75°C.
