108 16800 Series Portable Logic Analyzers Service Guide

5 Troubleshooting

10 Click Run, and ensure that an eye is found for each bit.

11 Click OK to close the Thresholds and Sample Positions

dialog.

12 Click OK to close the Analyzer Setup dialog.

13 Switch to the Listing window and run the logic analyzer.

14 Examine the listing. If the listing shows that the data

alternates between 0 AAAA and 1 5555, then the probe

and cable pass the test.

If the listing does not look similar to the figure, then

there is a possible problem with the cable or probe tip

assembly. Causes for cable test failures include:

• Open channel.

• Channel shorted to a neighboring channel.

• Channel shorted to either ground or a supply voltage.
