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

Description of command
This command configures the
READ:SUBarrays:POWer..., FETCh:SUBarrays:POWer...,
and
SAMPle: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 which are located on
a fixed, equidistant grid with a step width of ¼ symbols. If <Start> does not coincide with a test point then the
range will start at the next test point that is larger than <Start>.
For <Mode> = IVAL, the <Samples> parameter is ignored and the CMU returns a single measurement value at
the abscissa value <Start>. If <Start> is located beween 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. 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.
Measured Values
The subsystem POWer:MSLot... contains the commands to measure the normal burst power, compare
it with the tolerances and retrieve the results. The subsystem corresponds to the graphical
measurement menu
Power.
