R&S FSP Instrument Functions
Analyzer Mode
• LEVEL: sorting according to level
The search range can be restricted by means of the LEFT LIMIT, RIGHT LIMIT and
THRESHOLD softkeys. The definition of the peak values can be modified using the
PEAK EXCURSION softkey. The MKR->TRACE softkey in the main menu is used to
select the trace for searching peak values.
In single sweep mode, opening the list performs a single search at the end of the
sweep. The
NEW SEARCH softkey triggers a new sweep, determines the peak val-
ues of the trace at the end of the sweep and enters them in the list.
In continuous sweep mode, the peak search on the current trace starts as soon as
the sweep starts. This allows peak list functionality on averaged or max holded
traces in continuous mode.
Use the PEAK LIST OFF key to delete the list from the screen.

SORT MODE
(FREQ LEVEL)
The SORT MODE (FREQ LEVEL) softkey defines the position of the peak values in
the list:
• FREQ: sorting in ascending order of frequency values (time values if span = 0)
• LEVEL: sorting according to level
Remote command:
CALC:MARK:FUNC:FPE:SORT X;
PEAK
EXCURSION
With level measurements, the PEAK EXCURSION softkey allows the minimum
amount to be entered by which a signal must decrease or increase in order to be
recognized as a maximum by the peak search function.
Values between 0 dB and 80 dB may be entered, the resolution being 0.1 dB
Remote command:
CALC:MARK:PEXC 6dB
