[SENSe:]LIST:RANGe<ri>[:FREQuency]:STOP <Frequency>
This command defines the stop frequency of a spurious emission measurement range.
Make sure to set an appropriate span. If you set a span that is
●
smaller than the span the sweep list covers, the R&S FSW will not measure the
ranges that are outside the span - results may be invalid.
●
greater than the span the sweep list covers, the R&S FSW will adjust the start fre-
quency of the first range and the stop frequency of the last range to the span
For more information see Chapter 7.7, "Spurious Emissions Measurement" ,
on page 280 .
