Example:
//Turn on the n dB marker function.
CALC:MARK:FUNC:NDBD:STAT ON
//Position two temporary markers 3 dB below a reference
marker.
CALC:MARK:FUNC:NDBD 3
//Query the frequency position of the n dB down markers; would
return e.g. 100000000,200000000
CALC:MARK:FUNC:NDBD:FREQ?
//Query the measurement result; would return e.g. 100000000
CALC:MARK:FUNC:NDBD:RES?
CALCulate<n>:MARKer<m>:FUNCtion:NOISe:RESult?
This command queries the result of the noise measurement.
To get a valid result, you have to perform a complete sweep with synchronization to
the sweep end before reading out the result. This is only possible in single sweep
mode.

Query only
CALCulate<n>:MARKer<m>:FUNCtion:NOISe[:STATe]
<State>
This command turns the noise measurement marker function on and off.
You can query the results of the noise power density at the marker position with
CALCulate<n>:MARKer<m>:FUNCtion:NOISe:RESult?
