To test the threshold accuracy
Testing the threshold accuracy verifies the performance of the following specification:
•
Clock and data channel threshold accuracy.
These instructions include detailed steps for testing the threshold settings of pod 1.
After testing pod 1, connect and test pod 2. To test pod 2, follow the detailed steps
for pod 1, substituting the pod 2 for pod 1 in the instructions.
Each threshold test tells you to record the voltage reading in the performance test
record located at the end of this chapter. To check if each test passed, verify that the
voltage reading you record is within the limits listed on the performance test record.

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.
