GUIDED PROBE

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 on the pin to …..

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.

13.6          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.
