Operation Verification Test Verification Tests
Operation Verification Test
The procedures in this section are used to provide a high level of confidence that
the module is meeting published specifications. The Operation Verification test is
the same as the Performance Verification test and is suitable for checkout after
performing repairs.
The Operation Verification Test is performed by completing the Digital Test (Test
2-1) as described in the Performance Verification test procedures.
Performance Verification Tests
The procedure in this section is used to test the module’s electrical performance
using the specifications in Appendix A — Specifications of the Keysight E1458A
User’s Manual as the performance standard.
The Performance Verification test is a test of each data line and three of the
handshake lines on each port. The test uses the module’s capability for direct
read-back of the data and control lines. This test does not check output current
specifications or the ability to correctly handshake. This test is sufficient to
determine that the module is operating within specifications. This test is suitable
for incoming inspection, troubleshooting, and preventive maintenance.
Test 2-1: Digital I/O Module Test
This test verifies that all ports meet the specification for the module.
