Description of command
These commands are always queries. They output the burst power versus time in a fixed ¼- bit pattern and in the
subranges defined by means of the
CONFigure:SUBarrays:POWer
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
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.
The calculation of current, average, minimum, and maximum results is explained in chapter 3 (cf. display mode ).

Description of command
This command is always a query. It indicates whether and in which way the tolerances for the burst power (see
command above) have been exceeded. The following messages may be output for the value
Matching :
INV invalid
MATC matching
NMAT not matching
OUT out of range
NTR no trigger
NRAM not ramping (burst not found)
OFLW overflow
UFLW underflow
NTSC no training sequence code
OFF off

Description of command
This command is always a query. If a bit is set in the two returned values the corresponding section of the limit
lines is exceeded.
