Show Alignment Statistics
Shows alignment information you can use to ensure that the instrument is operating in a specific manner.
The Show Alignment Statistics screen is where you can view time and temperature information.
Values which are displayed are only updated when the Show Alignment Statistics screen is invoked, they
are not updated while the Show Alignment Statistics screen is being displayed. The remote commands
which access this information obtain current values.
:CAL:RF
:CALibration:RF? returns 0 if successful
:CALibration:RF? returns 1 if failed (including interfering user signal)
While Align Now, RF 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 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.
Initializes the time for the Last Align Now, RF Time.
Records the temperature for the Last Align Now, RF Temperature.
Bits 11, 12, or 14 may be set in the Status Questionable Calibration register.
