5 System Functions
System
: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.
Couplings
Initializes the time for the Last Align Now, RF Time.
Records the temperature for the Last Align Now, RF Temperature.
Status Bits/OPC
dependencies
Bits 11, 12, or 14 may be set in the Status Questionable Calibration register.

Remote Command
:CALibration:RF:NPENding
Example
CAL:RF:NPEN
Notes
:CALibration:RF:NPENding is the same as :CALibration:RF
including all conditions, status register bits, except that this scpi command does not BLOCK the scpi
session, so the user should use status register bits to query if the calibration is successfully
completed or not.
Typical usage is:
1):CALibration:RF:NPENding (Start a RF calibration)
2):STATus:OPERation:CONDition? (If bit 0 is set, then the system is doing calibration, the user should
do re-query until this bit is cleared )
3):STATus:QUEStionable:CALibration:CONDition? ( to check if there are any errors/failures in
previous calibration procedure)

Source (Weekly use)
Accesses source alignment processes that are immediate action operations. They perform complete
operations and run until they are complete.
Immediately executes an IQ alignment, and power level alignment. The instrument stops any sequence of
the source, performs the alignment, then restarts the sequence from the beginning.
This alignment corrects slow-rate drift which does not impair specifications for time periods shorter than
one week. Thus, it is required to perform this alignment on a weekly basis to maintain specifications. This
alignment typically takes >2 minutes to complete.
