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
alignments can be called during overhead time when the device-under-test is exchanged.

An interfering user signal may prevent automatic alignment of the RF
subsystem. If this occurs, the Error Condition message "Align skipped: 50
MHz interference" or "Align skipped: 4.8 GHz interference" is reported, the
Status Questionable Calibration bit 11 is set, and the alignment proceeds.
When a subsequent alignment of the RF subsystem succeeds, either by the
next cycle of automatic alignment or from an
Condition and Status Questionable Calibration bit 11 are cleared.
