4.6 Alignments
:CALibration:RFPSelector:ONLY?
Example
:CAL:RFPS:ONLY
Notes Query returns 0 if successful, or 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 clears Bits 1 and 2 in the Status Questionable Calibration
Extended Needed register and Bits 0 and 1 in Status Questionable Calibration Extended Failure
register
A failure encountered during alignment sets the Error Condition “20 Hz to 3.6 GHz Alignment Failure”,
sets Bits 1 and 2 in the Status Questionable Calibration Extended Needed register, and Bit 9 in Status
Questionable Calibration register
Dependencies Only appears in N9048B. Sending the SCPI command or query in other models generates an error
This key is grayed-out if the instrument is displaying an “Align Now All required” message. If you press
the key while it is grayed-out, you will see the informational message, “Align Now All required first”

dependencies
Bit 8 or 9 may be set in the Status Questionable Calibration register
Bit 1 and 2 may be set in the Status Questionable Calibration Extended Needed register
Bit 0 and 1 may be set in the Status Questionable Calibration Extended Failure register
4.6.2.8 Align Now External Mixer
Immediately executes an alignment of the External Mixer that is plugged into the
USB port. The instrument stops any measurement currently underway, performs the
alignment, then restarts the measurement from the beginning (similar to pressing
the Restart key). As this alignment calibrates the LO power to the mixer, this is
considered an LO alignment; and failure is classified as an LO alignment failure.
The query (:CALibration:EMIXer?) invokes the alignment of the External Mixer
and returns a success or failure value.
Remote Command
:CALibration:EMIXer
:CALibration:EMIXer?
Example
:CAL:EMIX
Notes Returns 0 if successful, or 1 if failed
While Align Now External Mixer is performing the alignment, Bit 0 in the Status Operation register is
set. Completion, or termination, clears Bit 0 in the Status Operation register
This command is sequential; it must complete before further SCPI commands are processed.
