The gap channels can be hidden if they do not reach a minimum size, or deactivated
entirely. This enhances the result display, as fewer lines and bars are displayed. If gap
channels are deactivated, the power results are not calculated and thus are not shown
in the Result Summary table.
Furthermore, channel names for all TX, adjacent, and alternate channels are now user-
definable.
Channel power results
The Result Summary for MSR signal measurements is similar to the table for common
signals (see
Chapter 7.3.2, "Channel Power Results"
on page 144). However, the Tx
channel results are grouped by sub blocks, and sub block totals are provided instead
of a total Tx channel power. Instead of the individual channel frequency offsets, the
absolute center frequencies are indicated for the transmit channels.
The CACLR and ACLR power results for each gap channel are appended at the end of
the table. The CACLR results are calculated as the power in the gap channel divided
by the power sum of the two closest transmission channels to either side of it.

Restrictions and dependencies
As the signal structure in multi-standard radio signals can vary considerably, you can
define the channels very flexibly for the ACLR measurement with the R&S
FSV/A. No
checks or limitations are implemented concerning the channel definitions, apart from
the maximum number of channels to be defined. Thus, you are not notified if transmit
channels for a specific sub block lie outside the defined frequency range for the sub
block, or if transmit and gap channels overlap.
