R&S FSH
Measuring the channel power of continuously modulated signals
1145.5973.12 4.35
E-14
The R&S FSH displays the softkey menu for setting the channel power measurement. Two vertical lines
in the measurement diagram indicate the channel bandwidth. The measured channel power is shown in
large letters below the measurement diagram.
The default setting is power measurement for 3GPP WCDMA signals.
Selecting the standard
The R&S FSH has a channel power measurement default setting for various standards. It is also
possible to define and save user-specified configurations.
Press the STANDARD softkey.
A submenu with the available standards opens.
Select the standard you want using the rotary knob
or the cursor keys.
Confirm your selection with the ENTER key or the
STANDARD softkey.
The R&S FSH sets the selected standard. The optimal
span, resolution bandwidth, video bandwidth, sweep
time and detector for the standard are selected
automatically.
If USER is selected, the R&S FSH sets the last channel power measurement setting used in the USER
mode. The R&S FSH automatically makes changes to the setting so that it is again available when the
USER standard is called again.
The following should be noted when changes to the settings are made:
•
The span is always coupled to the channel bandwidth. When changes are made, the R&S FSH
automatically sets the appropriate span.
•
The resolution bandwidth should be between 1 % and 4 % of the channel bandwidth. This means
that the channel power measurement has good selectivity with respect to adjacent channels.
