System
GHz interference” are cleared, the Error Condition “Align Now, RF required” is cleared, and bits 11 and 12
are cleared in the Status Questionable Calibration register
Align Now, All can be interrupted by pressing the Cancel (ESC) front-panel key or remotely with Device
Clear followed by the :ABORt SCPI command. When this occurs the Error Condition message “Align Now,
All required” is generated, and bit 14 is set in the Status Questionable Condition register. This is because
new alignment data may be employed for an individual subsystem, but not a cohesive set of data for all
subsystems.
In many cases, you might find it more convenient to change alignments to Normal, instead of executing
Align Now, All. When the Auto Align process transitions to Normal, the analyzer will immediately start to
update only the alignments that have expired, thus efficiently restoring the alignment process.
Key Path

Mode All
Remote Command
:CALibration[:ALL]
:CALibration[:ALL]?
Example :CAL
Notes :CALibration[:ALL]? returns 0 if successful
:CALibration[:ALL]? returns 1 if failed
:CALibration[:ALL]? is the same as *CAL?
While Align Now, All is performing the alignment, bit 0 in the Status Operation register is set.
Completion, or termination, will clear bit 0 in the Status Operation register.
This command is sequential; it must complete before further SCPI commands are processed.
Interrupting the alignment from remote is accomplished by invoking Device Clear followed by the
:ABORt command.
Successful completion will clear bit 14 in the Status Questionable Calibration register.
An interfering user signal is not grounds for failure of Align Now, All. However, bits 11 and 12 are set
in the Status Questionable Calibration register to indicate Align Now, RF is required.
An interfering user supplied signal will result in the instrument requiring an Align Now, RF with the
interfering signal removed.
Couplings Initializes the time for the Last Align Now, All Time.
Records the temperature for the Last Align Now, All Temperature.
If Align RF component succeeded, initializes the time for the Last Align Now, RF Time.
If Align RF component succeeded, records the temperature for the Last Align Now, RF Temperature.

Bits 11, 12, or 14 may be set in the Status Questionable Calibration register.
