Threshold

Accuracy Test

Description: This performance test verifies the threshold accuracy within the

three ranges stated in the specification.

Specification:

Threshold accuracy: 150 mV accuracy over the range -2.0 to + 2.0 volts; 300 mV

accuracy over the ranges -9.9 to -2.1 volts and + 2.1 to + 9.9 volts.

Equipment:

Power Supply .................................... HP 6216B

Test Connector (1)......................... see figure 3-1

Procedure:

1. Connect the test equipment as in figure 3-35.

Note In this setup, only eight channels are tested at a time to minimize loading. Ground

lead must be grounded to ensure accurate test results.

2. Assign the pod under test to Analyzer 1 in System Configuration as in

previous figure 3-31.

3. Configure Timing Format Specification for User Defined pod threshold of

0.0 V for the pod under test and assign the lower eight bits in the bit

assignment field as in figure 3-36. Refer to steps a and b if unfamiliar with

menu.

a. Move cursor to Pod Threshold field and SELECT. Move cursor to

User-defined field and SELECT. Enter the appropriate voltage

threshold.
