Description of comm
These commands are always queries. They return the burst power versus time in a fixed ¼- bit pattern. The
number of measured values is 668, corresponding to a time range of
–10 bit to 156 ¾ bit.
The calculation of current, average, minimum and maximum results is explained in chapter 3 (cf. display mode ).

Description of command
These commands are always queries. They return the burst power versus time in a fixed ¼- bit pattern and in the
subranges defined by means of the
CONFigure:SUBarrays:POWer[:NORMal][:GMSK]:MPR
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...
command group described above.
The
CONFigure:SUBarrays:POWer[:NORMal][:GMSK]:MPR
command defines a maximum of 32
subranges. If one of the statistical modes
(ARIThmetical, MINimum, MAXimum)
is set, only one value is
returned by subrange.
The calculation of current, average, minimum, and maximum results is explained in chapter 3 (cf. display mode ).
