or forward power display, the R&S FSH provides both average power and peak envelope power. Use
the FWRD PWR DISPLAY softkey in the Power Sensor menu to switch between the two.
 Press the FWRD PWR DISPLAY softkey.
 Select PEAK ENVELOPE from the menu using the
rotary knob or the cursor keys.
 Confirm your selection with the ENTER key or by

The R&S FSH displays the set weighting under the heading forward power on the screen:
Forward power (AVG) = average power
Forward power (PEP) = peak envelope power
Selecting the unit for the power readout
The R&S FSH displays the measured forward power as a logarithmic level value in dBm (relative value)
or as a linear value in W or mW (absolute value). Moreover, a reference level can be defined relative to
which the R&S FSH indicates the level difference in dB. Load matching is indicated as return loss in dB
or as voltage standing wave ratio (VSWR). In addition, the absolutely reflected power can be displayed
in W, or the reflected level in dBm.
 Press the UNIT softkey.
The menu for selecting the units for forward power and
reflected power display opens.
 Using the rotary knob or the cursor keys, select the
unit for the power readout.
For the forward power, the following units can be
selected:
dBm
W
dB REL
For the reflected power or the reflection, the following
units can be selected:
dBm
W
VSWR
dB (return loss)
