This recovery mechanism is used to fix system- level

problems – including damage done by viruses or

previously- installed software, problems with operating

system bugchecks (blue screen), etc.

Self Test

The logic analyzer does very little self test unless it is explicitly

run by the user. As previously mentioned, the system BIOS

does some hardware self test before turning control over to the

operating system.

Once a user logs into the system and runs the logic analyzer GUI

application software, self tests can be run by clicking on the

"Help" menu within the application and then selecting "Self

Test".

All self tests are consolidated into a single self test dialog.

The self test dialog contains a pane which allows the user to

select the "test suite" and a pane which allows the user to select

a specific test within that suite – or all of the tests. The tests

can be run once or repetitively. Each card will have its own

suite of tests. The frame hardware itself has a suite called

"System".

At the bottom of the self test dialog is a results pane. The

reporting level (how verbose the tests are) can be controlled

using a slider bar at the top of the dialog. At the very least, each

test should report that it is running and what the final status of

each test was (pass or fail). Increasing the reporting level and

re- running certain tests may help isolate a specific hardware

failure in the event that a test fails.
