SELF TEST DIAGNOSTIC PROGRAM
The Self Test diagnostic program allows the terminal to test itself and identify any
errors it finds
.
The Self Test error messages help locate the probable source of the
problem.
You can use the Self Test diagnostic program to identify a bad module
,
allowing you
to return that module to Tektronix for repair or replacement without incurring the
cost of a service call.
LEVELS OF SELF TEST
The terminal has three Self Test
levels:
•
Power-Up Self Test- Runs automatically every time the terminal is turned on or
reset. It performs a quick check of terminal circuitry before allowing the terminal
to be
used.
Power-Up Self Test takes approximately 15 seconds to complete
,
and requires no user interaction.
•
Extended Self Test- Contains all the tests performed by Power-Up Self Test
,
plus more extensive tests of terminal
circuitry,
particularly
memory.
Extended
Self Test takes about four minutes to complete
.
It requires user response at the
end of the test.
•
Adjustment Self Test- Displays a menu of tests and patterns
.
You can check or
adjust specific parts of the terminal as well as the terminal 's interaction with a
peripheral.
Figure E-1 illustrates how the three levels of Self Test are related.
