Fluke 9100A - Information About GFI

INFORMATION ABOUT GFI 6.2. -
GFI is normally used for automated troubleshooting of a UUT
after it fails a test. GFI uses stored information about the UUT
which a programmer stores in files in the 91OOA/9105A system.
GFI troubleshoots by backtracing: it starts with a bad output and
then works backwards to find the defective component. A
defective component is one that has good inputs but produces
the wrong output.
When you run GFI, you have to specify a starting point on the
UUT in the form of a component name and pin. You can get
this information from:
0
Any person who knows enough about the UUT to suggest
a starting point based on the results of previous tests.
l
A GFI suggestion list containing hints generated by an
automated test; the list suggests one or more locations at
which GFI could begin backtracing. Viewing the hint list
involves pressing the GFI key, the SUGGEST softkey, _
and the ENTER key.
The most promising suggestions are at the top of the
suggestion list. As GFI runs, it updates the list.
6-2
As GFI backtraces through a UUT, it generates a summary
which classifies each component in the backtracing path as
good, bad, or untested. Viewing the summary involves
pressing the GFI key, the SUMMARY softkey, and the ENTER
key.
