Limit Check
During an ACLR measurement, the power values can be checked whether they
exceed user-defined or standard-defined limits. A relative or absolute limit can be
defined, or both. Both limit types are considered, regardless whether the measured lev-
els are absolute or relative values. The check of both limit values can be activated
independently. If any active limit value is exceeded, the measured value is displayed in
red and marked by a preceding asterisk in the result table.
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 760).

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.
