A failure encountered during alignment will generate the Error Condition message “Characterize
Preselector failure” and set bit 3 in the STATus:QUEStionable:CALibration:EXTended:FAILure status
register. Successful completion of Characterize Preselector will clear this Condition. It will also begin
the elapsed time counter for Last Characterize Preselector Time, and capture the Last Characterize
Preselector Temperature.
The last Characterize Preselector Time and Temperature survives across the power cycle as this
operation is performed infrequently.
NOTE The Characterize Preselector function can be interrupted by pressing the Cancel
(ESC) front-panel key or remotely with Device Clear followed by the :ABORt
SCPI command. None of the new characterization data is then used. 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.
Key Path: System, Alignments, Advanced
Mode: All
Remote Command: :CALibration:YTF
:CALibration:YTF?
Example: :CAL:YTF
Notes: :CALibration:YTF? returns 0 if successful
:CALibration:YTF? returns 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, will clear
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 will clear bit 9 in the Status Questionable Calibration
register.
A failure encountered during alignment will generate the Error Condition
message “Characterize Preselector failed” and set bit 9 in the Status
Questionable Calibration register.
For Options that support frequencies > 3.6 GHz only.
Dependencies: This key 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.
