However, since the old characterization data is purged at the beginning of the
characterization, you now have an uncharacterized preselector. You should re-
execute this function and allow it to finish before making any further preselected
measurements.
Remote Command
:CALibration:YTF
:CALibration:YTF?
Example
:CAL:YTF
Notes :CALibration:YTF? returns 0 if successful, or 1 if failed (including interfering user signal)
While Advanced, Characterize Preselector is performing the alignment, Bit 0 in the Status Operation
register is set. Completion, or termination, clears Bit 0 in the Status Operation register
This command is sequential; it must complete before further SCPI commands are processed.
Interrupting the alignment from remote is accomplished by invoking Device Clear followed by the
:ABORt command
Successful completion clears Bit 9 in the Status Questionable Calibration register
A failure encountered during alignment generates the Error Condition message “Characterize
Preselector failed” and sets Bit 9 in the Status Questionable Calibration register
For Options that support frequencies > 3.6 GHz only
Dependencies This control does not appear in models that do not contain preselectors. In these models the SCPI
command is accepted without error, but no action is taken
Couplings Initializes the time for the Last Characterize Preselector Time
Records the temperature for the Last Characterize Preselector Temperature
Overlapped Command
Remote
Command
:CALibration:YTF:NPENding
Example
:CAL:YTF:NPEN
Notes :CALibration:YTF:NPENding is the same as :CALibration:YTF, including all conditions,
status register bits, except that this SCPI command does not block the SCPI session, so you should use
status register bits to query if the calibration is successfully completed or not
Typical usage is:
1.
:CALibration:YTF:NPENding (Start a YTF calibration)
2.
:STATus:OPERation:CONDition? (Check if the calibration is completed or not, If Bit 0 is
set, then the system is doing calibration, and you should repeat this query until the bit is cleared)
3.
:STATus:QUEStionable:CALibration:EXTended:FAILure:CONDition? (Check
whether Bit 2 is set. If this bit is set, that means there are some errors in previous internal source
calibration)
