Adjustment Procedures
TLA7AXX Logic Analyzer Module Service Manual
5- 13
NOTE
. Make sure that the alignment pin on the P6860 or P6880 probe head is
aligned with the hole on the test fixture. Tighten the probe head screws by
alternating between them until they are finger tight (no more than 1 in-lbs of
torque).
5.
If you are using a P6810 probe, make sure that you connect the ground or
low side of the lead sets to the GND side of the connectors on the test
fixture. Connect the clock/qualifier leads to the DESKEW REF connector;
make sure that you connect the ground side or the “--” side to the square pins
with the GND label. The single ground wire does not need to be connected.
6. Power on the test fixture and allow it to warm up for 30 minutes before
continuing the the adjustment procedures.
