"All" alignment (weekly use)

This alignment of all RF subsystems in the TRX is sufficient to maintain
specified performance, provided that:
1. The TRX's internal temperature has not drifted more than 5
2. No more than 7 days have elapsed since the previous "All" alignment
3. No more than 8 hours have elapsed since the previous "Fast" alignment (or
The "All" alignment typically takes less than 15 minutes to run.
To run the alignment, select System Settings> Alignments > Align Now >
Align Now All, or send the SCPI command:

Description
Perform all possible alignments, to get the best RF and IF performance for both the
source and the receiver.
Perform all alignments needed to get the best RF and IF performance for the source.
Perform all alignments needed to get the best RF and IF performance for the analyzer.
To save time, perform most of the source and analyzer alignments.
Perform only the LO Leakage relative alignments, for both the source and the analyzer.
previous "All" alignment
"All" alignment).
The alignment process requires a 45-minute preliminary warm-up period, after
applying power or after restarting the XSA application (when the application is
not running, power is not applied to the TRXs; therefore an application shutdown
has the same effect on alignment as a power shutdown).
Make sure there is not an interfering signal being applied to the RFIO ports while
the alignment is running. This can cause at least a portion of the alignment
process to be skipped; you will see an error message (such as "Align Analyzer
skipped"), and will have to re-run that portion of the process.
