To obtain the true power, the video bandwidth (VBW) too should
be selected to be greater than the resolution bandwidth (RBW).
Otherwise, an averaging effect caused by video bandlimiting
comes into play before the RMS value is calculated.
Both automatic operation and manual operation are available for setting the detector. In automatic
operation, the R&S FSH selects the detector that is suitable for the trace mode that is set. In manual
operation, the selected detector is always maintained regardless of the trace mode.
Setting of the detector in automatic operation:
Trace mode Detector
Clear/Write Auto Peak
Average Sample
Max Hold Max Peak
Min Hold Min Peak
Operating sequence:
¾ Press the TRACE key.
¾ Press the DETECTOR softkey.
The submenu for selecting the detector opens.
If automatic operation has been selected, the AUTO
COUPLED menu item is highlighted in green and the
R&S FSH displays the detector that is set to match the
trace mode that is set.
To switch automatic operation on or off:
¾ Using the cursor keys or rotary knob, select AUTO
COUPLED from the menu.
¾ Using the ENTER key or the DETECTOR softkey,
switch automatic operation on or off.
When automatic operation is switched on, the
R&S FSH also sets the detector that matches the trace
mode that is set.
To set the detector manually:
¾ Using the cursor keys or the rotary knob, select the detector you want and confirm by pressing the
ENTER key or the DETECTOR softkey.
The R&S FSH indicates the detector that has been selected in the top left-hand corner of the screen
(Detect: Auto Pk in Fig. above). If AUTO COUPLED is switched on and a detector that does not
accommodate automatic operation is set, the R&S FSH will switch automatic operation off.
