Agilent 8472A Point Contact Crystal Detector

The HP 8472A Crystal Detector is a 50Ω (nominal) device designed for measurement use in coaxial systems. The instrument converts RF power levels applied to the 50Ω input connector into proportional values of dc voltage.  The instrument measures relative power up to 100 mW and has a BNC female connector for the output jack which allows the detected output to be connected to a SWR meter.
