R&S ESU Instrument Functions
Analyzer Mode
CENTER =
MKR FREQ
The CENTER = MKR FREQ softkey sets the center frequency to the current marker
or delta marker frequency.
A signal can thus be set to the center of the frequency display range, for example,
so that it can then be examined in detail with a smaller span.
The softkey is not available in the time domain (zero span).
Remote command: CALC:MARK:FUNC:CENT
Example
A spectrum is displayed with a large span after PRESET. A signal off the center is to
be examined in detail:
REF LEVEL =
MKR LVL
The REF LEVEL = MKR LVL softkey sets the reference level to the current marker
level.
Remote command: CALC:MARK:FUNC:REF
Example
A spectrum is displayed with a large span after PRESET. A signal off the center is to
be examined in detail:
NEXT PEAK
The NEXT PEAK softkey sets the active marker/delta marker to the next lower max-
imum of the selected trace.
Remote command: CALC:MARK:MAX:NEXT
CALC:DELT:MAX:NEXT
[PRESET] R&S ESU is set to the default setting.
[MKR->] MARKER 1 is switched on and automatically jumps to
the largest signal of the trace.
[CENTER=MKR FREQ] The center frequency is set to the marker frequency. The
span is adapted in such a way that the minimum fre-
quency (= 0 Hz) or the maximum frequency is not
exceeded.
[SPAN] The span can, for example, be reduced using the rotary
knob.
