R&S FSH Measuring the occupied bandwidth

Renaming the USER standard:
The setting for the USER standard can be assigned a user-defined name. The name entered as the
USER standard also appears on the screen, thus making it possible to document the setting along with
the measurement.
Press the STANDARD softkey.
A table with the available standards opens.
Select Rename USER with the rotary knob or the
cursor keys.
Confirm your selection with the ENTER key or the
STANDARD softkey.
The R&S FSH will open the input window for the name
of the USER standard.
Using the numeric keys, enter a name.
Press the ENTER key to complete the entry.
When the STANDARD menu is called, the entered
name appears under USER (e.g. DAB (USER)). The
name also appears at the top right-hand corner of the
screen after the USER standard is selected.
Using the R&S FSH View control software, additional standards can be generated and permanently
loaded into the R&S FSH. You can also delete the factory-set standards provided in the instrument if
you do not need them. The R&S FSH then offers only the standards you require.
Setting the reference level
When selecting the reference level, ensure that the R&S FSH is not overdriven. As the power is
measured with a resolution bandwidth that is small in comparison with the signal bandwidth, the
R&S FSH may still be overdriven even though the trace is within the measurement diagram. To prevent
the R&S FSH from being overdriven, the signal can be measured at the largest resolution bandwidth
possible using the peak detector. If this setting is selected, the trace may not exceed the reference
level.
To simplify operation and to prevent incorrect measurements, the R&S FSH has an automatic routine
for setting the reference level.
