Performing external RF power measurements

This instrument performs radio output power measurement with the use of optional external power
sensors including JD730 series power sensors. It serves as the highly accurate RF power meter and
gives wider range of power measurement.

Connecting a cable

There are two types of power sensors. Directional power sensors are used in in-service power
measurement. Terminating power sensors are used in out-of-service power measurement.
