Troubleshooting
(The GFI Key)
INTRODUCTION
6.1.
The GFI (Guided Fault Isolation) key lets you use a powerful
program-built into the 9
lOOA/
105A system-to troubleshoot
a defective UUT. You need no special knowledge of either GFI
or the UUT.
Running GFI involves pressing the GFI key and the RUN
softkey.
You then specify a UUT component name and pin and
press the ENTER key. GFI starts running from the specified
UUT location.
As GFI runs, you may be asked to probe a specific pin on a
UUT component or to clip over an entire UUT component. This
section describes how to probe or clip over components.
