CALCulate Subsystem
This subsystem is used to perform post-acquisition data processing. In effect, the
collection of new data triggers the CALCulate subsystem. In this instrument, the
primary functions in this subsystem are markers and limits.
NdBpoints
:CALCulate:BWIDth|BANDwidth:NDB <rel_ampl>
:CALCulate:BWIDth|BANDwidth:NDB?
Selects the power level, below the peak of the signal, at which the signal
bandwidth will be measured by the markers.
:CALCulate:BWIDth|BANDwidth[:STATe] must be ON.
To query the result of NdBpoints, use the command

:CALCulate:BWIDth|BANDwidth:RESult?
Returns the measured bandwidth at the power level defined by
:CALCulate:BWIDth:NDB. –100 is returned if
:CALCulate:BWIDth|BANDwidth[:STATe] is off, or when a result is not
available. Refer to CALCulate:BWIDth|BANDwidth[:STATe] for an
