Description of command
These commands are always queries. They return the power versus frequency in the subranges defined by
means of the CONFigure:SUBarrays:SPECtrum command. In the default setting of the configuration com-
mand the READ:SUBarrays..., FETCh:SUBarrays..., and SAMPle:SUBarrays... command group
is equivalent to the READ:ARRay..., FETCh:ARRay..., and SAMPle:ARRay... command group de-
scribed above.
The CONFigure:SUBarrays:SPECtrum command defines a maximum of 32 subranges. If one of the statisti-
cal modes (ARIThmetical, MINimum, MAXimum) or IVAL is set, only one value is returned by subrange.
The calculation of CURRent, AVERage, MINimum, and MAXimum results is explained in Chapter 3 (see Dis-
play Mode).
