Subsystem SUBarrays:POWer
The subsystem SUBarrays:POWer defines the measurement range and the type of output values.

Description of command
This command configures the READ:SUBarrays:POWer..., FETCh:SUBarrays:POWer..., and SAM-
Ple:SUBarrays:POWer commands. It restricts the measurement to up to 32 subranges where either all
measurement results (the number of which is given by the second numerical parameter) or a single statistical
value is returned. The subranges are defined by the start time and the number of test points to be measured.
For <Mode> = IVAL, the <Samples> parameter is ignored and the CMU returns a single measurement value cor-
responding to the abscissa value <Start>. If <Start> is located between two test points with valid results then the
result is calculated from the results at these two adjacent test points by linear interpolation.
The subranges may overlap but must be within the total range of the POWer measurement defined via
[SENSe:]POWer:TIME:DELay and [SENSe:]POWer:TIME:SPAN. Test points outside this range are not
measured (result NAN) and do not enter into the ARIThmetical, MINimum and MAXimum values.
By default, only one range corresponding to the total measurement range is used and all measurement values
are returned.
