4.6 Alignments
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 High Band alignment. You are responsible for checking the
temperature shift since last Align Now, Align High Band, to determine whether the
High Band alignment needs to be executed.
Remote Command
:CALibration:INTernal:HBANd[:ALL]
:CALibration:INTernal:HBANd[:ALL]?
Example
:CAL:INT:HBAN
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 external time for the Last Align High Band Now, All Time
Records the temperature for the Last Align High Band Now, All Temperature
4.6.3 Path Delay Calibration
Path Delay Calibration is used to remove the time delay differences between
multiple power channels of a module.
Dependencies Only available in VXT modules M9410A/11A
Only for modules with matched Digital board hardware version, which means the modules are in same
FPGA version
The matched hardware version information is in below table
Digital board Hardware version Matched module
M9410A 2,3,4,6,10,11 Yes
M9410A 12, 13 Yes
M9411A 18 Yes
M9411A 20,21 Yes
M9411A 12,13 Yes
M9411A 0,1,2,3,4,6,10,11 Yes
4.6.3.1 Source Path Delay Calibration
Accesses the Source Path Delay Calibration processes, which are immediate-action
operations and perform complete operations, running until they are complete.
