CALCulate Subsystem R&S FSL
1300.2519.12 6.76 E-11
Example
CALC:MARK:FUNC:NDBD 3dB
Sets the level spacing to 3 dB.
Characteristics
*RST value: 6dB
SCPI: device–specific
Mode
A
CALCulate<1|2>:MARKer<1...4>:FUNCtion:NDBDown:FREQuency?
This command queries the values of the two temporary markers for span>0. The frequency
values are separated by comma and output in ascending order.
A complete sweep with synchronization to sweep end must be performed between switching on
the function and querying the measured value to obtain a correct query result. This is only
possible in single sweep mode.
The numeric suffixes <1|2> and <1...4> are irrelevant for this command.
This command is only a query and therefore has no *RST value.
Example
INIT:CONT OFF
Switches to single sweep mode.
CALC:MARK:FUNC:NDBD ON
Switches on the n dB down function.
INIT;*WAI
Starts a sweep and waits for the end.
CALC:MARK:FUNC:NDBD:FREQ?
Outputs the frequencies of the temporary markers.
Characteristics
*RST value: –
SCPI: device–specific
Mode
A
CALCulate<1|2>:MARKer<1...4>:FUNCtion:NDBDown:QFACtor?
This command queries the Q factor (quality) of the measured bandwidth for span>0.
This command is only a query and therefore has no *RST value.
This command is available from firmware version 1.80.
Example
INIT:CONT OFF
Switches to single sweep mode.
CALC:MARK:FUNC:NDBD ON
Switches on the n dB down function.
INIT;*WAI
Starts a sweep and waits for the end.
CALC:MARK:FUNC:NDBD:QFAC?
Queries the Q factor of the measured bandwidth.
