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 MEAS menus are located in “SENSe Subsystem” on

page 94.

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.

*RST: –3 dB

Range: –80 dB to –1 dB

Remarks: Refer to :CALCulate:BWIDth|BANDwidth[:STATe] for an

explanation of this marker function.

Key Access: > More > N dB Points

NdBresults

:CALCulate:BWIDth|BANDwidth:RESult?

Returns the measured bandwidth at the power level defined

by :CALCulate:BWIDth:NDB?. 0 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.
