Chapter 3: Testing Performance

To test the threshold accuracy

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 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.

Each threshold test tells you to record a pass/fail reading in the performance test record located at the end of this chapter.

Equipment Required

Equipment	Critical Specifications	Recommended Model/Part
Digital Multimeter	0.1 mV resolution, 0.005% accuracy	3458A
Function Generator	Accuracy (5)(10-6) frequency,	33250A
	DC offset voltage ±1.5 V
BNC-Banana Cable		11001-60001
BNC Tee		1250-0781

BNC Test Connector, 17x2

Set up the equipment

1If you have not already done so, do the procedure “To set up the test equipment and the logic analyzer” on page 23.

2Set up the DC source to deliver a DC voltage on the output:

a In the function generator Utility menu, activate the DC Level. All AC voltage functions will be disabled.

b Enable the high impedance load under the Output Setup menu.

3Using a BNC-banana cable, connect the voltmeter to one side of the BNC Tee.

4Connect the BNC Tee to the output of the DC source. Set up the logic analyzer.
