5 System Functions
System
There is no alert available for the source alignment. The operators have the responsibility to check
temperature shift since last Align Now, Source to determine if the source alignment needs to be executed.

All
Remote Command
:CALibration:INTernal:SOURce[:ALL]
:CALibration:INTernal:SOURce[:ALL]?
Example
:CAL:INT:SOUR
Notes
:CAL:SOUR? Initiates an Alignment and returns 0 if successful
:CAL:SOUR? Initiates an Alignment and returns 1 if failed
Couplings
Initializes the time for the Last Align Source Now, All Time.
Records the temperature for the Last Align Source Now, All Temperature.

Mode
All
Remote Command
:CALibration:INTernal:SOURce[:ALL]:NPENding
Example
CAL:INT:SOUR:NPEN
Notes
:CALibration:INTernal:SOURce[:ALL]:NPENding is the same as :CALibration:INTernal:SOURce[:ALL]
including all conditions, status register bits, except that this scpi command does not BLOCK the scpi
session, so the user should use status register bits to query if the calibration is successfully
completed or not.
Typical usage is:
1):CALibration:INTernal:SOURce:NPENding (start an internal source calibration)
2):STATus:OPERation:CONDition? (Check if the calibration is completed or not, If bit 0 is set, then
the system is doing calibration, the user should repeat this scpi query until the bit is cleared )
3):STATus:QUEStionable:CALibration:EXTended:FAILure:CONDition? (Check if bit 14 is set or not. If
this bit is set, that means there are some errors in previous internal source calibration)

IF Alignment (Weekly use)
Immediately executes an alignment of the IF subsystem which includes both the source and the analyzer in
the TRX module. The instrument stops any measurement currently underway, perform the alignment, and
then restart the measurement from the beginning (similar to pressing the Restart key). This alignment
corrects slow-rate which the drift does not impair specifications for time periods shorter than one week.
Thus, it is required to perform this alignment on a weekly basis to maintain specifications. This alignment
typically takes >4 minutes to complete.
A failure of IF will set the Error Condition “Align IF failed” and set bit 4 in the Status Questionable
Calibration register. A failure will not employ new IF alignment data.
Successful completion of IF will clear the Error Condition “Align IF failed” and clear bit 6 in the Status
Questionable Calibration register.
