Service Key Descriptions
This will invokes a text editor with the alignment log file loaded. The
log can be viewed or saved to an external media or drive.
The text editor can be closed without a mouse or external keyboard
by pressing ALT front-panel key, then arrow down to highlight Exit,
then press Enter.
Align Log Mode
The alignment system places information about each alignment
performed into a log. The log can be configured to operate in clear or
append mode.
In Clear mode the log only contains information on the last alignment
performed; the log is cleared with each alignment performed.
In Append mode each new alignment appends to the log. In append
mode, care must be taken by the operator to not allow the log to
grow to a size that would inhibit system operation.
Subsystem
This menu allows invoking individual components of the complete
alignments that are available on the System, Alignment, Align Now menu
that is accessible to the normal user.
ADC
Immediately executes an alignment of the ADC subsystem. The
instrument will stop any measurement currently underway, perform
the alignment, and then restart the measurement from the beginning.
A failure of ADC will set the Error Condition “Align ADC failed”. A
failure will not employ new ADC alignment data.
Successful completion of ADC will clear the Error Condition “Align
ADC failed”.
The Advisory Event “Alignment complete” is displayed when the
alignment is complete.
Align ADC can be interrupted by pressing the Cancel (ESC)
front-panel key.
LO
Immediately executes an alignment of the LO subsystem. The
instrument will stop any measurement currently underway, perform
the alignment, and then restart the measurement from the beginning.
A failure of LO will set the Error Condition “Align LO failed”. A failure
will not employ new LO alignment data.
Successful completion of LO will clear the Error Condition “Align LO
failed”.
