All but RF
(In MXE the key label is "All but RF (not including RF Presel)")
Immediately executes an alignment of all subsystems except the RF subsystem . The instrument will stop
any measurement currently underway, perform the alignment, and then restart the measurement from the
beginning (similar to pressing the Restart key). This can be used to align portions of the instrument that are
not impacted by an interfering user input signal.
This operation might be chosen instead of All if you do not want the device under test to experience a large
change in input impedance, such as a temporary open circuit at the analyzer input.
The query form of the remote commands (:CALibration:NRF?) will invoke the alignment and return a
success or failure value.
Successful completion of Align Now, All but RF will clear the "Align Now, All required" Error Condition, and
clear bit 14 in the Status Questionable Calibration register. If "Align Now, All required" was in effect prior to
executing the All but RF, the Error Condition message "Align Now, RF required" is generated and bit 12 in
the Status Questionable Calibration register is set. It will also begin the elapsed time counter for Last Align
Now, All Time, and capture the Last Align Now, All Temperature.
Align Now, All but RF 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 used for an individual subsystem, but not a full new set of data for all
subsystems.
In models with the RF Preselector, such as the N9038A, the "All but RF" alignment will execute an
alignment of all subsystems except the RF subsystem of the Spectrum Analyzer, as well as the system
gain of the RF Preselector.

*CAL? returns 1 if failed
:CALibration[:ALL]? is the same as *CAL?
See additional remarks described with :CALibration[:ALL]?
Everything about :CALibration[:ALL]? is synonymous with *CAL? including all conditions, status

:CAL:NRF
:CALibration:NRF? returns 0 if successful
:CALibration:NRF? returns 1 if failed
While Align Now, All but RF 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.
