All but RF
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

This operation might be chosen instead of
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.

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 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 0 if successful
*CAL? returns 1 if failed
:CALibration[:ALL]? is the same as *CAL?
