Calculate Subsystem - Agilent Technologies ESA Series User's/Programmer's Reference

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. CALCulate subsystem
commands used for measurements in the
located in Volume 2.
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.
NOTE To query the result of NdBpoints, use the command
:CALCulate:BWIDth|BANDwidth:RESult?

: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
explanation of this marker function.
