MKR -> - Analyzer R&S ESCI
1166.6004.12 4.138 E-1
PEAK
The PEAK softkey sets the active marker/delta marker to the peak of the
trace.
If no marker is active when MKR-> menu is called, MARKER 1 is automati-
cally switched on and the peak search is performed.
IEC/IEEE-bus commands: CALC:MARK:MAX
CALC:DELT:MAX
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 ex-
ample, so that it can then be examined in detail with a smaller span.
The softkey is not available in the time domain (zero span).
IEC/IEEE-bus 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:
[PRESET] R&S ESCI 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 frequency
(= 0 Hz) or the maximum frequency is not exceeded.
[SPAN] The span can, for example, be reduced using the rollkey.
REF LEVEL
=MKR LVL
The REF LEVEL = MKR LVL softkey sets the reference level to the current
marker level.
IEC/IEEE-bus 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:
[PRESET] R&S ESCI 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 frequency
(= 0 Hz) or the maximum frequency is not exceeded.
[REF LEVEL
= MKR LVL] The reference level is set to the measured marker level.
[SPAN] The span can, for example, be reduced using the rollkey.
