Command description
These commands are always queries. They return the results of the spectrum measurement at 560 equidistant
test points. The measurement range is defined by the commands [SENSe:]SPECtrum:FREQuency:CENTer
and [SENSe:]SPECtrum:FREQuency: SPAN or by [SENSe:]SPECtrum:FREQuency:STARt and
[SENSe:]SPECtrum: FREQuency:STOP.
Note: The number of test points may be reduced at very narrow measurement ranges.
