Standard
The main measurement settings can be stored as a standard file. When such a stand-
ard is loaded, the required channel and general measurement settings are automati-
cally set on the R&S
FSW. However, the settings can be changed. Predefined stand-
ards are available for standard measurements, but standard files with user-defined
configurations can also be created.
Note: If the "Multi-Standard Radio" standard is selected, the "ACLR Setup" dialog box
is replaced by the "MSR ACLR Setup" dialog box (see chapter 5.3.5, "MSR ACLR
Configuration" , on page 158).
If any other predefined standard (or "NONE") is selected, the "ACLR Setup" dialog box
is restored (see
chapter 5.3.4, "Channel Power Configuration" , on page 148).
Note that changes in the configuration are not stored when the dialog boxes are
exchanged.
Predefined Standards ← Standard
Predefined standards contain the main measurement settings for standard measure-
ments. When such a standard is loaded, the required channel settings are automati-
cally set on the R&S
FSW. However, the settings can be changed.
The predefined standards contain the following settings:
●
Channel bandwidths
●
Channel spacings
●
Detector
●
Trace Average setting
●
Resolution Bandwidth (RBW)
●
Weighting Filter
Predefined standards can be selected via the "CP/ACLR Standard" softkey in the "CH
Power" menu or in the "General Settings" tab of the "CP/ACLR Setup" dialog box.
For details on the available standards see chapter 5.3.9, "Reference: Predefined CP/
ACLR Standards" , on page 183.

User-Defined Standards ← Standard
In addition to the predefined standards you can save your own standards with your
specific measurement settings in an xml file so you can use them again at a later time.
User-defined standards are stored on the instrument in the
C:\R_S\instr\acp_std
directory.
A sample file is provided for an MSR ACLR measurement (MSR_ACLRExample.xml).
It sets up the measurement for the MSR signal generator waveform described in the
file
C:\R_S\instr\user\waveform\MSRA_GSM_WCDMA_LET_GSM.wv
.
Note that ACLR user standards are not supported for Fast ACLR and multicarrier
ACLR measurements.
