To test the threshold accuracy
Testing the threshold accuracy verifies the performance of the following specification:
•
Clock and data channel threshold accuracy.
Multicard modules must be reconfigured as one-card modules for this test.
These instructions include detailed steps for testing the threshold settings of pod 1.
After testing pod 1, connect and test the rest of the pods one at a time. To test the
next pod, follow the detailed steps for pod 1, substituting the next pod for pod 1 in
the instructions.

Set up the equipment
1
Turn on the equipment required and the logic analyzer. Let them warm up for
30 minutes before beginning the test.
2
Set up the function generator.
a Set up the function generator to provide a DC offset voltage at the Main Signal output.
b Disable any AC voltage to the function generator output, and enable the high voltage
output.
c Monitor the function generator DC output voltage with the multimeter.
