R&S ESCI CALCulate:DELTamarker Subsystem
1166.6004.12 6.11 E-1
CALCulate<1|2>:DELTamarker<1 to 4>:X:RELative?
This command queries the frequency (span > 0) or time (span = 0) of the selected delta marker
relative to marker 1 or to the reference position ( for CALCulate:DELTamarker:FUNCtion
:FIXed:STATe ON). The command activates the corresponding delta marker, if necessary.
Example: "CALC:DELT3:X:REL?" 'Outputs the frequency of delta marker 3 in
'screen B relative to marker 1 or relative to the
'reference position.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A, FM
CALCulate<1|2>:DELTamarker<1 to 4>:Y?
This command queries the measured value of the selected delta marker in the indicated
measurement window. The corresponding delta marker will be activated, if necessary. The output is
always a relative value referred to marker 1 or to the reference position (reference fixed active).
To obtain a valid query result, a complete sweep with synchronization to the sweep end must be
performed between the activation of the delta marker and the query of the y value. This is only
possible in single sweep mode. In receiver mode, the markers can be only activated after a scan is
carried out.
Depending on the unit defined with CALC:UNIT or on the activated measuring functions, the query
result is output in the units below:
• DBM | DBPW | DBUV | DBMV | DBUA: Output unit DB
• WATT | VOLT | AMPere: Output unit W | V | A
• Statistics function (APD or CCDF) on: Dimensionless output
• Result display FM (FS-K7): Hz
• Result display RF POWER (FS-K7): dB
• Result display SPECTRUM (FS-K7): dB
Example: "INIT:CONT OFF" 'Switches to single-sweep mode.
"CALC:DELT2 ON" 'Switches on delta marker 2 in screen A.
"INIT;*WAI" 'Starts a sweep and waits for its end.
"CALC:DELT2:Y?" 'Outputs measurement value of delta marker 2 in
'screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A, FM
CALCulate<1|2>:DELTamarker<1 to 4>:MAXimum[:PEAK]
This command positions the delta marker to the current maximum value on the measured curve. If
necessary, the corresponding delta marker will be activated first.
Example: "CALC2:DELT3:MAX" 'Sets delta marker 3 in screen B to the
'maximum value of the associated trace.
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A, FM
This command is an event and therefore has no *RST value and no query.
