System
Normal
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.
When Auto Align, Normal is selected the Auto Align Off time is set to zero.
When Auto Align, Normal is selected the Settings Panel indicates ALIGN AUTO.

Mode All
Example :CAL:AUTO ON
Notes 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.

Status Bits/OPC
dependencies 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 Align Now, RF, the Error Condition and Status Questionable
Calibration bit 11 are cleared.
Initial S/W Revision Prior to A.02.00
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.
