26 16800 Series Portable Logic Analyzers Service Guide
3 Testing Performance
Directions for performing power-up tests and the logic
acquisition card’s manual performance verification tests
(against the specifications listed on page 15) are given in
this chapter.
The logic analyzer is considered performance- verified if the
power- up tests, the self- tests, and the manual performance
tests have passed. The procedures in this chapter indicate
what constitutes a “Pass” status for each of the tests.
To perform the power-up tests
The logic analyzer automatically performs power- up tests
when you apply power to the instrument. Any errors are
reported in the boot dialogue. Serious errors will interrupt
the boot process.
The power- up tests are designed to complement the
instrument on- line Self-Tests. Tests that are performed
during powerup are not repeated in the Self-Tests.
A keyboard and mouse must be connected to the logic
analyzer to observe the results of the power- up tests.
1 Exit all logic analysis sessions.
2 Press the power switch for about 1 second and release,
wait for the the unit to power off.
3 After a few seconds, turn the power switch back on.
Observe the boot dialogue for the following:
• Ensure all of the installed memory is recognized.
• Any error messages.
• Interrupt of the boot process with or without error
message.
A complete transcript of the boot dialogue is in chapter 8,
"Theory of Operation."
4 During initialization, check for any failures.
If an error or an interrupt occurs, refer to Chapter 5,
“Troubleshooting.”
