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.
Key Path: System, Alignments, RF Preselector, Align Now
Mode: All
Remote Command: :CALibration:RFPSelector:CONDucted
:CALibration:RFPSelector:CONDucted?
Example: :CAL:RFPS:COND
Notes: :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.
For model N9038A only.
Dependencies: This key does not appear in other than N9038A models, setting or querying
the SCPI will generate an error.
Couplings: Initializes the time for the Last Align Conducted Now, Conducted Time.
Records the temperature for the Last Align Conducted Now, Conducted
Temperature.
