Description

 

The 8472B crystal detector is a 50 Ω (nominal) device designed for

 

measurement use in coaxial systems.

Features

The instrument converts RF power levels applied to the 50 Ω input

 

connector into proportional values of dc voltage.

The instrument measures relative power up to 200 mW and has a BNC female connector for the output jack which allows the detected output to be connected to a SWR meter.

The output voltage polarity is negative, unless Option 003 is selected.

The frequency range of the detector is 10 MHz to 18 GHz.

Options The 8472B crystal detector is available with the following options. Refer to Table 1 for further descriptions.

Option 001: Matched pair of detectors

Option 002: Optimum square law load

Option 003: Positive polarity output

Option 100: Female OSSM type output connector

Mating Connectors

The mating output connector used with the crystal detector must be a male BNC connector for the standard output connector or an OSSM male connector for Option 100.

The mating RF input connector must be a female SMA connector.

CAUTION

SMA connectors have a limited life in applications that require repeated

 

connecting and disconnecting. In-series adapters should be used for such

 

applications.
