Description of command

FW vers.

This command configures the READ:SUBarrays:SPECtrum..., FETCh:SUBarrays:SPECtrum..., and SAMPle:SUBarrays:SPECtrum 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 frequency 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 corresponding 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 SPECtrum measurement defined by the commands [SENSe:]SPECtrum:FREQuency:CENTer and [SENSe:]SPECtrum: FREQuency:SPAN or by [SENSe:]SPECtrum:FREQuency:STARt and [SENSe:]SPECtrum: FREQuency:STOP. 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.
