R&S FSMR CALCulate Subsystem
1313.9723.12 6.1-55 E-1
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NDBDown:STATe ON | OFF
This command switches the "N dB Down" function on or off in the selected measurement window.
Marker 1 is activated first, if necessary. The numeric suffix <1 to 4> is irrelevant for this command.
Example: "
CALC:MARK:FUNC:NDBD:STAT ON"
'Switches on the N-dB-down function in
'screen A.
Characteristics: *RST value: OFF
SCPI: device-specific
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NDBDown:TIME?
This command queries the two time values of the "N dB Down" markers in the specified
measurement window. The suffix <1 to 4> has no meaning with this command. The two time values
are output in ascending order, separated by commas.
To obtain a valid query response, a complete sweep with synchronization to the sweep end must
have been performed in between activating the function and querying the measurement results. This
is possible only 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:TIME?"
'Outputs the time values of the temporary
markers in screen A.
Characteristics : *RST value: -
SCPI: device-specific
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NOISe:RESult?
This command queries the result of the noise measurement.
A complete sweep with synchronization to the 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:MARK2 ON"
'Switches on marker 2 in screen A.
"CALC:MARK:FUNC:NOIS ON"
'Switches on noise measurement in screen A.
"INIT;*WAI"
'Starts a sweep and waits for the end.
"CALC:MARK2:NOIS:RES?"
'Outputs the noise result of marker 2 in
'screen A.
Characteristics: *RST value: -
SCPI: device-specific
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NOISe[:STATe] ON | OFF
This command switches the noise measurement on or off for all markers of the indicated
measurement window. The noise power density is measured at the position of the markers. The
result can be queried with
CALCulate:MARKer:FUNCtion:NOISe:RESult?
.
Example:
"CALC2:MARK:FUNC:NOIS ON"
'Switches on the noise measurement for
'screen B.
Characteristics: *RST value: OFF
SCPI: device-specific
