Center =Mkr Freq (span > 0)
Sets the center frequency to the current marker or delta marker frequency. A signal
can thus be set to as center frequency, for example to examine it in detail with a
smaller span.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:CENTer
Ref Lvl =Mkr Lvl
Sets the reference level to the current marker level.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:REFerence
Auto Max Peak/Auto Min Peak
Adds an automatic peak search action for marker 1 at the end of each particular
sweep. This function may be used during adjustments of a device under test to keep
track of the current peak marker position and level.
The current marker search limit settings

Switches the frequency range limit for the marker search functions on or off.

Peak................................................................................... 412
LO..................................................................................................................412
The minimum frequency included in the peak search range is ≥ 5 ×
resolution bandwidth (RBW).
Due to the interference by the first local oscillator to the first inter-
mediate frequency at the input mixer, the LO is represented as a sig-
nal at 0 Hz. To avoid the peak marker jumping to the LO signal at 0
Hz, this frequency is excluded from the peak search.
No restriction to the search range. The frequency 0 Hz is included in
the marker search functions.
