Measurements using the power sensor
For even more accurate power measurements, the R&S FSH can be used with the Power Sensors
R&S FSH-Z1 and R&S FSH-Z18. Their frequency ranges are 10 MHz to 8 GHz and 10 MHz to 18 GHz,
respectively. This means that both sine signals and modulated signals can be measured precisely over
a large dynamic range.
Connecting the power sensor
The Power Sensors R&S FSH-Z1 and -Z18 are controlled and powered via a special interface. Connect
the power sensor cable to the R&S FSH’s power sensor connector and screw into position. The DUT is
connected to the N-connector on the power sensor.

The continuous power applied to the power sensor’s input must not exceed 400 mW
(26 dBm). Short ( 10
<
s) power peaks up to 1 W (30 dBm) are however permissible.
Higher input powers may destroy the sensor. An attenuator pad must be used to ensure
that the maximum permissible power for the sensor is never exceeded when
measurements are made on high-power transmitters.
Measurement:
The POWER SENSOR function turns the R&S FSH into a wideband power meter. Then, it always
measures the power of the whole signal from 10 MHz to 8 GHz or from 10 MHz to 18 GHz, in most
cases the signal shape having no effect on the measurement.
