System

See additional remarks described with :CALibration[:ALL]?

Everything about :CALibration[:ALL]? is synonymous with *CAL? including all conditions, status
register bits, and couplings

Initial S/W Revision

Prior to A.02.00

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 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.
