Initial S/W Revision
Align Now, 30 MHz to 3.6 GHz
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:RADiated?) will invoke the alignment
of the RF Preselector on Radiated Band and return a success or failure value. Successful completion will
clear the "Align 30 MHz to 3.6 GHz required" Error Condition, and clear the bit 2 in the Status Questionable
Calibration Extended Needed register. The elapsed time counter will begin for Last Align Now, Radiated
Time, and the temperature is captured for the Last Align Now, Radiated 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 30 MHz to 3.6 GHz 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 30 MHz to 3.6 GHz required" Error Condition will appear when this alignment has expired. User
is now responsible to perform the Align Now, 30 MHz to 3.6 GHz 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.

:CAL:RFPS:COND
For model N9038A only.
:CALibration:RFPSelector:CONDucted? Return 0 if successful
:CALibration:RFPSelector:CONDucted? Return 1 if failed
When Align 20 Hz to 30 MHz 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 will clear bit 1 in the Status Questionable Calibration Extended
Needed register and bit 0 in Status Questionable Calibration Extended Failure register.
A failure encountered during alignment will set the Error Condition "20 Hz to 30 MHz Alignment
Failure" and set both bit 1 in the Status Questionable Calibration Extended Needed register and bit 9
in Status Questionable Calibration register.
This key does not appear in other than N9038A models, setting or querying the SCPI will generate an
error.
Initializes the time for the Last Align Conducted Now, Conducted Time.
Records the temperature for the Last Align Conducted Now, Conducted Temperature.
Bit 8 or 9 may be set in the Status Questionable Calibration register.
Bit 1 may be set in the Status Questionable Calibration Extended Needed register.
Bit 0 may be set in the Status Questionable Calibration Extended Failure register.
