CALCulate<1|2>:MARKer<1...4>:FUNCtion:NDBDown:RESult?
This command queries the frequency spacing (bandwidth) of the N-dB-down markers in the selected
measurement window. The numeric suffix <1...4> is irrelevant for this command.
A complete sweep with synchronization to sweep end must be performed between switching on the
function and querying the measured value in order to obtain a valid query result. This is only possible
in single-sweep mode.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK:FUNC:NDBD ON"
'Switches on the n-dB-down function in screen A.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:FUNC:NDBD:RES?"
'Outputs the measured value of 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...4>:FUNCtion:NDBDown:FREQuency?
This command queries the two frequencies of the N-dB-down marker in the selected measurement
window. The numeric suffix <1...4> is irrelevant for this command. The two 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 valid query result. This is only possible in single-
sweep mode.
Example:
"INIT:CONT OFF"
'Switches to single-sweep mode.
"CALC:MARK:FUNC:NDBD ON"
'Switches on the n-dB-down function in screen A.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK:FUNC:NDBD:FREQ?"
'Outputs the frequencies of the temporary markers in screen A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A
This command is only a query and therefore has no *RST value.
