General Troubleshooting

5In the Analysis System Self Tests dialog, select the self test options:

•Include interactive tests — causes interactive tests to appear in the selection lists.

•Run repetitively — runs the selected tests repetitively until you click Stop.

•Stop on fail — if you are running multiple tests or running tests repetitively, this causes the tests to stop if there is a failure.

•Double-click item to start — lets you double-click a test to start it.

6Set the reporting level.

Higher levels produce increasingly verbose output.

7Select the tests you want to run.

8Click Start.

As the tests are running, the results are reported in the lower part of the dialog and saved to a log file.

Two 9-channel comparators interpret the incoming data and clock signals as either high or low, depending on where the user-programmable threshold is set. The threshold voltage of each pod is individually programmed, and the voltage selected applies to the clock channel as well as the data channels of each pod A field programmable gate array FPGA bridges the 1394 interface to the rest of the acquisition board components.
