CALCulate:MARKer Subsystem R&S ESCI
1166.6004.12 6.42 E-1
CALCulate<1|2>:MARKer<1 to 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 queríed with CALCulate:MARKer:COUNt:FREQuency?.
Frequency counting is possible only for one marker at a time for each 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
CALCulate<1|2>:MARKer<1 to 4>:COUNt:RESolution 0.1 | 1 | 10 | 100 | 1000 | 10000 Hz
This command specifies the resolution of the frequency counter in the selected measurement
window.The setting is independent of the selected marker, i.e. the numeric suffix in MARKer<1 to 4>
is irrelevant.
Example: "CALC:MARK:COUN:RES 1kHz" 'Sets the resolution of the frequency counter
'to 1 kHz.
Characteristics: *RST value: 1kHz
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1 to 4>:COUNt:FREQuency?
This command queries the result of the frequency counter for the indicated marker in the selected
measurement window. Before the command, the frequency counter should be switched on and a
complete measurement performed to obtain a valid count result. Therefore, a single sweep with
synchronization must be performed between switching on the frequency counter and querying the
count result.
Example: "INIT:CONT OFF" 'Switches to single-sweep mode.
"CALC:MARK2 ON" 'Switches marker 2 in screen A.
"CALC:MARK2:COUN ON" 'Switches the frequency counter for marker 2.
"INIT;*WAI" 'Starts a sweep and waits for the end.
"CALC:MARK2:COUN:FREQ?" 'Outputs the measured value of marker 2 in
'screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is only a query and therefore has no *RST value.
CALCulate<1|2>:MARKer<1 to 4>:COUPled[:STATe] ON | OFF
This command switches the coupling of the receiver frequency to the marker on or off.
Example: "CALC:MARK:COUP ON" marker coupling is switched on
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: R
The numeric suffix in MARKer<1 to 4> is irrelevant.
