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.
¾ Press the POWER DISPLAY softkey.
The menu for selecting the units for forward power and
reflected power display opens.
¾ Using the rotary knob or the cursor keys, select the
parameter for which a unit is to be entered.
¾ Confirm the parameter with the ENTER key or the
POWER DISPLAY softkey.
A submenu with the available units opens.
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)
When the dB REL... unit is selected, an entry box for
the reference level opens.
¾ Enter the reference level (REFERENCE) using the
number keys and terminate the entry with the
appropriate unit, or change the reference level
using the rotary knob or the cursor keys.
The current level reading can be defined as the reference level simply by pressing the ->REF softkey.
