RF Preselector

This menu and all of its submenus are only available in models with the RF Preselector, such as the
N9038A.

Initial S/W Revision
Align Now
Accesses alignment processes that are immediate action operations. They perform complete operations
and run until they are complete.

Align Now, 20 Hz to 30 MHz
Immediately executes an alignment of the receiver subsystem. The receiver will stop any measurement
currently underway, perform an Align Now All, then perform the RF Preselector alignment, and then restart
the measurement from the beginning (similar to pressing the Restart key).
The query form of the remote commands (:CALibration:RFPSelector:CONDucted?) will invoke the
alignment of the RF Preselector on Conducted Band and return a success or failure value. Successful
completion will clear the "Align 20 Hz to 30 MHz required" Error Condition, and clear the bit 1 in the Status
Questionable Calibration Extended Needed register. The elapsed time counter will begin for Last Align
Now, Conducted Time, and the temperature is captured for the Last Align Now, Conducted Temperature.
The alignment 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 "Align 20 Hz to 30
MHz required" is set because new alignment data may be employed for an individual subsystem, but not a
cohesive set of data for all subsystems.
The "Align 20 Hz to 30 MHz required" Error Condition will appear when this alignment has expired. User is
now responsible to perform the Align Now, 20 Hz to 30 MHz in order to keep the receiver in warranted
operation. This alignment can only be performed by user as it is not part of the Auto Align process.
