System Functions
System
NOTE It is recommended that the Folder provided is outside of the instrument (USB or
Mapped Network Drive).
Perform Restore (Remote Command Only)
Invokes an alignment data restore operation from the provided filename.
Advanced
Accesses alignment processes that are immediate action operations that perform operations that run until
complete. Advanced alignments are performed on an irregular basis, or require additional operator
interaction
Characterize Preselector
The Preselector tuning curve drifts over temperature and time. Recognize that the Amplitude, Presel
Center function adjusts the preselector for accurate amplitude measurements at an individual frequency.
Characterize Preselector improves the amplitude accuracy by ensuring the Preselector is approximately
centered at all frequencies without the use of the Amplitude, Presel Center function. Characterize
Preselector can be useful in situations where absolute amplitude accuracy is not of utmost importance,
and the throughput savings or convenience of not performing a Presel Center is desired. Presel Center is
required prior to any measurement for best (and warranted) amplitude accuracy.
Agilent recommends that the Characterize Preselector operation be performed yearly as part of any
calibration, but performing this operation every three months can be worthwhile.
Characterize Preselector immediately executes a characterization of the Preselector, which is a
YIG-tuned filter (YTF). The instrument stops any measurement currently underway, performs the
characterization, then restarts the measurement from the beginning (similar to pressing the Restart key).
The query form of the remote commands (:CALibration:YTF?) will invoke the alignment of the YTF
subsystem and return a success or failure value.
