Auto Align, Normal turns on the automatic alignment of all measurement systems. The Auto Align,
Normal selection maintains the instrument in warranted operation across varying temperature and over
time.
If the condition "Align Now, All required" is set, transition to Auto Align, Normal will perform the
required alignments and clear the "Align Now, All required" condition and then continue with further
alignments as required to maintain the instrument adequately aligned for warranted operation.

While Auto Align is executing, bit 0 of Status Operation register is set.
Auto Align is set to Off if Restore Align Data is invoked.

This is unaffected by Preset but is set to ON upon a "Restore System
Defaults->Align".

When Auto Align is executing, bit 0 in the Status Operational register is set.

:CAL:AUTO ON
Alignment processing as a result of the transition to Normal will be executed
sequentially. Thus, *OPC? or *WAI following CAL:AUTO ON will return
when the alignment processing is complete.
The presence of an external signal may interfere with the RF portion of the
alignment. If so, the Error Condition message "Align skipped: 50 MHz
interference" or "Align skipped: 4.8 GHz interference" is reported, and bit 11
is set in the Status Questionable Calibration register. After the interfering
signal is removed, subsequent alignment of the RF will clear the condition,
and clear bit 11 in the Status Questionable Calibration register.
