R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
6.5.6 CALCulate:MARKer Subsystem
The CALCulate:MARKer subsystem checks the marker functions in the instrument.
The measurement windows are selected via CALCulate1 (screen A) or 2 (screen B).
The subsystem is divided into the description of the general marker commands ( “General CALCulate:
MARKer:... Commands” on page 6.45 ) and of the marker functions ( “CALCulate:MARKer:FUNCtion
Subsystem” on page 6.54 ). The description of marker functions is subdivided again into the commands
for transient measurement ( “CALCulate:MARKer:FUNCtion:ADEMod Subsystem” on page 6.97 ), the
commands for harmonic distortion measurement ( “CALCulate:MARKer:FUNCtion:HARMonics Sub-
system” on page 6.66 ), for control of power measurement( “CALCulate:MARKer:FUNCtion:POWer Sub-
system” on page 6.69 ), for settings of signal track ( “CALCulate:MARKer:FUNCtion:STRack Subsystem”
on page 6.78 ) and for controlling the main power functions ( “CALCulate:MARKer:FUNCtion:SUMMary
Subsystem” on page 6.80 ).
6.5.6.1 General CALCulate:MARKer:... Commands
CALCulate<1|2>:MARKer<1...4>:AOFF
This command switches off all active markers in the indicated measurement window.
All delta markers and active marker/delta marker measurement functions are also switched off.
Example:
"CALC:MARK:AOFF"
'Switches off all markers in screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:MARKer<1...4>:COUNt ON | OFF
This command switches on or off the frequency counter at the marker position in the selected
measurement window. The count result is queried with
CALCulate:MARKer:COUNt:FREQuency?
.
Frequency counting is possible only for marker 1 in every measurement window. If it is activated for
another marker, it is automatically de-activated for the previous marker.
It should be noted that a complete sweep must be performed after switching on the frequency counter
to ensure that the frequency to be measured is actually reached. The synchronization to the sweep
end required for this is possible only in single-sweep mode.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK ON"
'Switches on marker 1 in screen A.
"CALC:MARK:COUN ON"
'Switches on the frequency counter for marker 1.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:COUN:FREQ?"
'Outputs the measured value in screen A.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
