Power Measurements Using the
Power Sensor

For highly accurate power measurements, the

R&S FSH provides the Power Sensor R&S FSH-Z1

or R&S FSH-Z18 as options. They measure power

in the span 10 MHz to 8 GHz or 10 MHz to 18 GHz,

respectively.

The Power Sensor is controlled and powered

via a special RS-232-C interface at the top of the

instrument.
