6 RLC Swept SA Measurement Front-Panel & SCPI Reference
System
The last Characterize Preselector Time and Temperature survives across the power cycle as this
operation is performed infrequently.
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.
Initial S/W Revision Prior to A.02.00
Timebase DAC
Allows control of the internal 10 MHz reference oscillator timebase. This may be used to adjust for
minor frequency alignment between the signal and the internal frequency reference. This
adjustment has no effect if the instrument is operating with an External Frequency Reference.
