13.0 GUIDED PROBE
13.1
The primary purpose of the guided probe is to verify fixture probe
contact continuity
from a node on the UUT, through the test fixture,
and down to the appropriate interface pin on the testhead.
13.2
To invoke the guided probe from a BT-BASIC window, click the mouse on
the “Stop”
softkey or
the “Stop” button on the operator keypad window.
13.3
At the BT-BASIC command line, type find
pins. This will clear the working
area of the
BT-BASIC window. Only two softkeys “Start”, F1 and
“Done”, F8 will be now be displayed. The
following message will appear:
Place the guided probe

13.4
Using the Board Graphics Viewer, locate the physical location of the
suspect node. To be probed.
13.5
Click the mouse on the “Start” sofkey or press F1 on the keyboard. The
node information of the point being probed will appear on the BT-BASIC
window.
Note: If no contact is reported for the node being
probed and you are certain that the correct point is being touched, then the
contact is open. Always attempt
reseating the test fixture on the test head and re-check the probe
contact. If the contact failure persists
contact the test engineering department for assistance.

When you have completed using the guided probe click the mouse on the
“Done” softkey of press F8 on the keyboard.
This will return you to the testplan that you were last using.
