Keysight N9020B - Mkr->Stop; Mkr->Ref Lvl

3 Spectrum Analyzer Mode
3.2 Swept SA Measurement
Dependencies Not available (control is grayed-out) when x-axis is the time domain
Couplings All the usual couplings associated with setting Start Freq apply
Mkr->Stop
Changes Stop Freq to the frequency of the selected marker. The marker stays at this
frequency, so it moves to the right edge of the display. In Delta marker mode, this
function sets the stop frequency to the x-axis value of the Delta marker.
If the currently selected marker is not on when this control is pressed, it is turned on
at the center of the screen as a Normal marker.
Remote Command
:CALCulate:MARKer[1]|2|…|24[:SET]:STOP
Example Set the stop frequency to the value (or delta value) of Marker 3:
:CALC:MARK3:STOP
Notes Sending this command selects the subopcoded marker
If specified marker is Off, this command turns it on at the center of the screen as a Normal marker
Dependencies Not available (control is grayed-out) when x-axis is the time domain
Couplings All the usual couplings associated with setting Stop Freq apply
Mkr->Ref Lvl
Sets Reference Level to the amplitude value of the selected marker, moving the
marked point to the reference level (top line of the graticule). The marker’s mode
(Normal, Delta, Fixed) does not matter in this case. For example, given a Delta
marker, if the Delta marker is the selected marker, its amplitude is applied to the
reference level. If the reference marker is selected, its amplitude is applied to the
reference level.
If the currently selected marker is not on when this control is pressed, it is turned on
at the center of the screen as a Normal marker, and its amplitude applied to the
reference level.
Remote
Command
:CALCulate:MARKer[1]|2|…|24[:SET]:RLEVel
Example Set Reference Level of the instrument to the amplitude of Marker 2:
:CALC:MARK2:RLEV
Notes Sending this command selects the subopcoded marker
If specified marker is Off, this command turns it on at the center of the screen as a Normal marker
Couplings All the usual couplings associated with setting Reference Level apply
Backwards
Compatibility
Mkr-> Ref Lvl behavior for a delta marker is slightly different from earlier models. ESA would calculate
the delta amplitude (difference between reference marker and delta marker in dB) and assign that value
