CALCulate Subsystem

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:BWIDthBANDwidth:NDB <rel_ampl>

:CALCulate:BWIDthBANDwidth:NDB?

Selects the power level, below the peak of the signal, at which the signal bandwidth will be measured by the markers. :CALCulate:BWIDthBANDwidth[:STATe] must be ON.

To query the result of NdBpoints, use the command

:CALCulate:BWIDthBANDwidth:RESult?

Factory Preset

 

and *RST:

–3 dB

Range:

–80 dB to –1 dB

Default Unit:

dB

Remarks:

Refer to :CALCulate:BWIDthBANDwidth[:STATe] for an

 

explanation of this marker function.

Front Panel

 

Access:

Peak Search (or Search), N dB Points

NdBresults

:CALCulate:BWIDthBANDwidth:RESult?

Returns the measured bandwidth at the power level defined by :CALCulate:BWIDth:NDB. –100 is returned if :CALCulate:BWIDthBANDwidth[:STATe] is off, or when a result is not available. Refer to CALCulate:BWIDthBANDwidth[:STATe] for an explanation of this marker function.

Range:

Real value less than the current frequency span

Default Unit:

Hz

Remarks:

When segmented sweep is on, a result will not be available

 

when the NDB marker crosses a segment boundary.
