Partial

Auto Align, Partial disables the full automatic alignment and the maintenance of warranted operation for
the benefit of improved measurement throughput. Accuracy is retained for the Resolution Bandwidth filters
and the IF Passband, which is critical to FFT accuracy, demodulation, and many measurement
applications. With Auto Align set to Partial, you are now responsible for maintaining warranted operation
by updating the alignments when they expire. The Auto Align, Alert mechanism will notify you when
alignments have expired. One solution to expired alignments is to perform the Align All, Now operation.
Another is to return the Auto Align selection to Normal.
Auto Align, Partial is recommended for measurements where the throughput is so important that a few
percent of improvement is more valued than an increase in the accuracy errors of a few tenths of a decibel.
One good application of Auto Align, Partial would be an automated environment where the alignments can
be called during overhead time when the device-under-test is exchanged.
When Auto Align, Partial is selected the elapsed time counter begins for Auto Align Off time.
When Auto Align, Partial is selected the Settings Panel indicates ALIGN PARTIAL with a warning icon. The
warning icon is to inform the operator that they are responsible for maintaining the warranted operation of
the instrument

Off
Auto Align, Off disables automatic alignment and the maintenance of warranted operation, for the benefit
of maximum measurement throughput. With Auto Align set to Off, you are now responsible for maintaining
warranted operation by updating the alignments when they expire. The Auto Align, Alert mechanism will
notify you when alignments have expired. One solution to expired alignments is to perform the Align All,
Now operation. Another is to return the Auto Align selection to Normal.
The Auto Align, Off setting is rarely the best choice, because Partial gives almost the same improvement in
throughput while maintaining the warranted performance for a much longer time. The choice is intended
for unusual circumstances such as the measurement of radar pulses where you might like the revisit time
to be as consistent as possible.
When Auto Align, Off is selected the Auto Align Off time is initialized and the elapsed time counter begins.
