CALCulate Subsyste m
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 marker s
and limits.
NdBpoint s
CALCulate :BWIDthIBANDwidth :NDB <rel_ampl>
CALCulate :BWIDthIBANDwidth :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 comman d

and *RST: -3 dB
Range:
-80 dB to -1 d B
Default Unit: dB
Remarks: Refer to : CALCulate :BWIDth ~ BANDwidth [ : STATe] for
an explanation of this marker function.

CALCulate :BWIDthIBANDwidth :RESult ?
Returns the measured bandwidth at the power level defined b y
CALCulate : BWIDth : NDB . -100 is returned if
: CALCulate : BWIDth ~ BANDwidth[ : STATe ] is off, or when a result is
not available .
Range : Real value less than the current frequency span
Default Unit: Hz
Remarks: Refer to CALCulate : BWIDth ~ BANDwidth [ : STATe] for an
explanation of this marker function .
