The results of the power limit checks are also indicated in the STAT:QUES:ACPL sta-
tus registry (see "STATus:QUEStionable:ACPLimit Register" on page 636).

Weighting Filters
Weighting filters allow you to determine the influence of individual channels on the total
measurement result. For each channel you can activate or deactivate the use of the
weighting filter and define an individual weighting factor ("Alpha" value).
Weighting filters are not available for all supported standards and cannot always be
defined manually where they are available.

Channel Names
In the R&S FSW's display, carrier channels are labelled "Tx" by default; the first neigh-
boring channel is labelled "Adj" (adjacent) channel; all others are labelled "Alt" (alter-
nate) channels. You can define user-specific channel names for each channel which
are displayed in the result diagram and result table.

5.3.5 MSR ACLR Configuration
ACLR measurements can also be performed on input containing multiple signals for
different communication standards. A new measurement standard is provided that
allows you to define multiple discontiguous transmit channels at specified frequencies,
independent from the selected center frequency. If the "Multi-Standard Radio" standard
