One-Button Measurement Functions
State Saved: The number of the selected marker is saved in instrument state.
Factory Preset: Marker 1
History: Added with ESA firmware revision A.07.00
Remote Command:
:CALCulate:PSTatistic:MARKer[1]|2|3|4[:STATe] OFF|ON|0|1
:CALCulate:PSTatistic:MARKer[1]|2|3|4[:STATe]?
Sets or queries the state of a marker. Setting a marker to state ON or 1 selects that
marker. Setting a m arker which is OFF to stat e ON or 1 puts it in Normal mode and places
it at the center of the display. Setting a marker to state OFF or 0 selects that marker and
turns it off. The response to the query will be 0 if OFF, 1 if ON.
Example: CALC:PST:MARK2 ON selects marker 2.
CALC:PST:MARK:STAT ON will not modify a marker that is already on.
2.9.2 Normal
Sets the control mode for the selected marker to Normal. If the marker is off, a single
marker is activated at the 0 dB point of the selected trace (see “Marker Trace” on
page 127). You can then adjust the selected marker using the numeric keypad, knob, or ⇑ ⇓
keys.
Key Path: Marker (after MEASURE, Power Stat CCDF is selected.)
Factory Preset: Off
History: Added with ESA firmware revision A.07.00
Remote Command:
See Volume 1, Core Spectrum Analyzer Functions User’s and Programmer’s Reference
guide.
Example: CALC:PST:MARK:MODE NORM selects marker 1 and sets it to Normal.
2.9.3 Delta
Sets the control mode for the selected marker to Delta. In Delta mode the display shows the
difference between the active (Delta) marker and a reference marker. When Delta mode is
selected the reference marker is placed at the current marker position, unless the marker
was OFF, in which case both the active marker and the reference marker are placed at 0 dB
point of the selected trace (see “Marker Trace” on page 127). You can adjust the trace point
of the active delta marker. Annotation in the active function block and in the upper-right
corner of the display indicates the power ratio (dB) difference and probability (percentage)
difference of the two markers.
Key Path: Marker (after MEASURE, Power Stat CCDF is selected.)
