Description of command
These commands are always queries. They output the off-carrier power due to switching in the subranges de-
fined by means of the
CONFigure:SUBarrays:SPECtrum:SWITching
command. In the default setting of the
configuration command the
READ:SUBarrays..., FETCh:SUBarrays..., and SAMPle:SUBarrays...
command group is equivalent to the
READ:ARRay..., FETCh:ARRay..., and SAMPle:ARRay...
com-
mand group described above.
The
CONFigure:SUBarrays:SPECtrum:SWITching
command defines a maximum of 32 subranges. If one
of the statistical modes
(ARIThmetical, MINimum, MAXimum)
is set, only one value is returned per
subrange.
