Description of command
These commands are always queries. They output the phase error versus time in a fixed ¼- bit pattern and in the
subranges defined by means of the
CONFigure:SUBarrays:MODulation[:PERRor][:GMSK]
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:MODulation[:PERRor][:GMSK]
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 ).
