R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
CALCulate<1|2>:DELTamarker<1...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.
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
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.
