4 System
4.6 Alignments
There is no alert for the External Mixer Path alignment. You are responsible for
checking the temperature shift since the last Align Now, External Mixer Path, to
determine whether the external mixer path alignment needs to be executed.
Remote Command
:CALibration:INTernal:EMPath
:CALibration:INTernal:EMPath?
Example
:CAL:INT:EMP
Notes The query initiates an alignment and returns 0 if successful, or 1 if failed
Dependencies Only appears in VXT models M9415A/16A when Option MXP is installed
Couplings Initializes the time for the Last Align External Mixer Path Now, All Time
Records the temperature for the Last Align External Mixer Path Now, All Temperature
4.6.2.22 Align Low Band
Accesses Low Band alignment processes that are immediate action operations.
They perform complete operations and run until they are complete. Low Band
Alignment covers frequencies from 380MHz to 4.3GHz of the non-external mixer
path.
NOTE
This alignment corrects slow-rate drift, which does not impair specifications for
time periods shorter than one week. Thus, you need only perform this alignment
on a weekly basis to maintain specifications. This alignment typically takes >2
minutes to complete.
There is no alert for the Low Band alignment. You are responsible for checking the
temperature shift since the last Align Now, Align Low Band, to determine whether
the Low Band alignment needs to be executed.
Remote Command
:CALibration:INTernal:LBANd[:ALL]
:CALibration:INTernal:LBANd[:ALL]?
Example
:CAL:INT:LBAN
Notes The query initiates an Alignment, and returns 0 if successful, or 1 if failed
Dependencies Only appears in VXT models M9415A/16A
Couplings Initializes the time for the Last Align Low Band Now, All Time
Records the temperature for the Last Align Low Band Now, All Temperature
4.6.2.23 Align High Band
Accesses High Band alignment processes that are immediate action operations.
They perform complete operations and run until they are complete. High Band
Alignment covers frequencies from 4.3 GHz to 12 GHz of the non-external mixer
path.
