The peak search is based on the current content of the trace buffer. Therefore, you
may encounter unexpected results in continuous or single sweep if you start a peak
search without the sweep being finished as parts of the trace may not have been
updated yet.
Remote command: INIT;*WAI;

CALC:MARK:FUNC:FPE:COUN?;
CALC:MARK:FUNC:FPE:Y?;
CALC:MARK:FUNC:FPE:X?
Activates and deactivates the peak list that is displayed below the diagram area.
The peak list is always available for a query in remote operation after a search has
been performed, even if it is inactive.
Remote command: CALC:MARK:FUNC:FPE:STAT ON | OFF
Activates or deactivates an automatic peak search. The R&S FSQ performs the
automatic peak search after it has finished a sweep.
If you need an update of the peak list prior to the end of the sweep, perform a new
search with the NEW SEARCH softkey.
Remote command: CALC:MARK:FUNC:FPE:SEAR:AUTO ON | OFF
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;
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
Opens a submenu to define peak search search limits.

The LEFT LIMIT and RIGHT LIMIT softkeys define the vertical lines F1/F2 in the frequency
domain (span > 0) and T1/T2 in the time domain (span = 0) between which
the search is carried out.
