ACLR measurement is also defined by the channel spacing, the bandwidth of adjacent
channels and the adjacent channel spacing.
The R&S Spectrum Rider supports measurements on up to 12 carrier channels and 12
adjacent channels to either side of the carrier. When measuring more than one carrier
or adjacent channels, the R&S Spectrum Rider shows the powers of each channel in a
list below the marker list. The channel itself is marked by red (transmission channels)
or green (adjacent channels) vertical lines.

The predefined standards are the same as for channel power measurements (3GPP
WCDMA, cdmaOne and CDMA2000 1x systems). However, you can also customize
the settings to set up the R&S Spectrum Rider for other radiocommunication stand-
ards. You can define the settings directly on the R&S Spectrum Rider or define and
manage them using the R&S InstrumentView software.
When customizing settings, make sure to consider the following points to get valid and
accurate measurement results:
