Service and Diagnostics Menus
Service Key Descriptions

Align

The Align Menu allows accessing Diagnostic capabilities of Alignment, and
invoking alignments for individual subsystems.
Diagnostic
The Diagnostic menu contains items for controlling the operating behavior of
Alignment and the Alignment reporting capabilities.
Visible Align
Controls the state of Visible Align. Visible Align replaces the "Aligning 1
or 10" messages with descriptive messages describing the alignment piece
begin executed.
Align Log...
Invokes Notepad with the Alignment Log loaded. The log can be viewed or
saved to an external media or drive. Notepad 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 the last 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 so large
as to inhibit system operation.
Subsystem
The Subsystem menu allows invoking individual components of the internal
alignments.
ADC
Immediately executes an alignment of the ADC subsystem. The instrument
will stop any measurement currently underway, perform the alignment, 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. When this occurs, no new ADC alignment data will be employed.
