Rf Presel Only (20 Hz To 3.6 Ghz) - Keysight x-series User Reference Manual

RF Presel Only (20 Hz to 3.6 GHz)

This key only appears in the MXE and immediately executes an alignment of the RF Preselector section.
The receiver will stop any measurement currently underway, perform the alignment, and then restart the
measurement from the beginning (similar to pressing the Restart key). ONLY the RF Preselector is aligned;
no Align Now All function is performed first.
The query form of the remote commands (:CALibration:RFPSelector:ONLY?) will invoke the alignment of
the RF Preselector on both Conducted and Radiated Band and return a success or failure value. Successful
completion will clear the "Align 20 Hz to 3.6 GHz required" Error Condition, and clear bit 1 and bit 2 in the
Status Questionable Calibration Extended Needed register.
The elapsed time counter will begin for Last Align Now, Conducted Time and Last Align Now Radiated Time
and the temperature is captured for Last Align Now, Conducted Temperature and 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 20
Hz 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 20 Hz to 3.6 GHz required" Error Condition will appear when this alignment has expired. The
user is now responsible to perform the Align Now, 20 Hz to 3.6 GHz in order to keep the receiver in
warranted operation. This alignment can only be performed by the user as it is not part of the Auto Align
process.

:CALibration:RFPSelector:ONLY? Return 0 if successful
:CALibration:RFPSelector:ONLY? Return 1 if failed
When Align 20 Hz to 3.6 GHz 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, bit 2 in the Status Questionable Calibration
Extended Needed register and bit 0, bit 1 in Status Questionable Calibration Extended Failure
register.
A failure encountered during alignment will set the Error Condition "20 Hz to 3.6 GHz Alignment
Failure" and set bit1, bit 2 in the Status Questionable Calibration Extended Needed register and bit 9
in Status Questionable Calibration register.
For model N9038A only.
This key does not appear in other than N9038A models, setting or querying the SCPI will generate an
error.
This key is grayed out if the analyzer is displaying an "Align Now All required" message. If the user
presses the key while it is grayed out they will receive the informational message, "Align Now All
required first."
