R&S FSH Power Meter
Using the Internal Power Meter
Operating Manual 1173.6275.12 - 30 144
4.3 Using the Internal Power Meter
The R&S FSH also supports power measurements without using a power sensor. In
that case, you can connect the DUT directly to the R&S FSH and still perform accurate
channel power measurements.
The screen layout is the same as is described in "Using a Power Sensor" on page 133.
Performing and configuring channel power measurements
The configuration of channel power measurements without a power sensor is similar to
measurements with a power meter.
The following features are available:
● Defining the frequency
● Zeroing the measurement
● Selecting the unit
● Defining the reference level
● Taking additional loss or gain into account
For more information see "Performing and Configuring Measurements" on page 136.
Defining the channel bandwidth
In addition, you can select the channel bandwidth.
► Press the MEAS key.
► Press the "Channel BW" softkey.
The R&S FSH opens an input field.
► Enter the required channel bandwidth.
The R&S FSH performs a measurement on the selected channel. Note that it is not
possible to change the measurement time, resolution bandwidth and frequency span.
