Description of command
These commands are always queries. They return the error vector magnitude vs. time at fixed, equidistant test
points. The number of measured values is 588, corresponding to a time range of 0 bit to 146 ¾ bit.
The calculation of
current, average, and mmax
(Min./Max.) results is explained in chapter 3 (see
display mode
).

V2.15
Description of command
These commands are always queries. They measure and return the error vector magnitude versus time in the
subranges defined by means of the
CONFigure:SUBarrays:MODulation:EVMagnitude:EPSK
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:EVMagnitude:EPSK
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 (see
display
mode
).
