4.8.11.5 Measurement of a Peak List
PEAK LIST
The PEAK LIST softkey allows the peak values of the trace to be determined and
entered in a list with 50 entries max. The order of the entries is defined by the SORT
MODE :
• FREQ: sorting in ascending order of frequency values (see screenshot); if span =
0, the entries are sorted in ascending order of time values
• 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.
