All but RF Preselector

This function only appears in the MXE, and is identical to the Align Now All (plus RF Presel) function
described above, except that the RF Preselector in the MXE is only partially aligned. Only the System Gain,
Mechanical attenuator and Electronic attenuator alignments on the RF Preselector path are aligned. The
purpose of these alignments is to improve the RF Preselector path amplitude variation compared to the
bypass path.

:CALibration:RF? returns 1 if failed (including interfering user signal)
While Align Now, 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.
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 clears the Error Conditions "Align skipped: 50 MHz interference" and "Align
skipped: 4800 MHz interference" and the Error Conditions "Align RF failed" and "Align Now, RF
required", and clears bits 3, 11, and 12 in the Status Questionable Calibration register.
A failure encountered during alignment will generate the Error Condition message "Align RF failed"
and set bit 3 in the Status Questionable Calibration register.
An interfering user signal will result in bits 11 and 12 to be 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.
Initializes the time for the Last Align Now, RF Time.
Records the temperature for the Last Align Now, RF Temperature.
Bits 11, 12, or 14 may be set in the Status Questionable Calibration register.
