8. Define the settings for the two (upper or lower) gap (CACLR) channels; since the
upper and lower channels are identical, it is only necessary to configure two chan-
nels.
● The spacing, defined as the distance from the outer edge of the sub block to
the left or right of the gap. The required spacing can be determined as follows:
Spacing = [CF of the gap channel] - [left sub block center] + ([RF bandwidth of
left sub block] /2)
● The bandwidth
● If necessary, a weighting filter
● Optionally, define
and activate
relative or absolute limits, or both, against which
the power levels of the channel are to be checked.
9. If power limits are defined and activated, activate global limit checking for the mea-
surement on the "Adj/Gap Channel Settings" tab.
10. Optionally, store the settings for the MSR ACLR measurement as a user-defined
"To store a user-defined configuration"
erwise the configuration will be lost when you select a different measurement
standard!

How to Manage User-Defined Configurations
You can define measurement configurations independently of a predefined standard
and save the current ACLR configuration as a "user standard" in an xml file. You can
then load the file and thus the settings again at a later time.
User-defined standards are not supported for "Fast ACLR" and multicarrier ACLR
measurements.
Compatibility to R&S FSP
User standards created on an analyzer of the R&S FSP family are compatible to the
R&S
FSW. User standards created on an R&S
FSW, however, are not necessarily
compatible to the analyzers of the R&S FSP family and may not work there.
To store a user-defined configuration
1. In the "Ch Power" menu, select the "CP / ACLR Config" softkey to display the
"ACLR Setup" dialog box.
2. Configure the measurement as required (see also
chapter 5.3.6.2, "How to Set up
3. In the "General Settings" tab, select the "Manage User Standards" button to display
the "Manage" dialog box.
4. Define a file name for the user standard and select its storage location.
By default, the xml file is stored in
C:\R_S\Instr\acp_std\
. However, you can
define any other storage location.
5. Select "Save".
