Test Validity

1. Meet expected measurements (Design data/Test Requirements)

2. Test System characterision

2.1. Calibrate systems, characterize interfacing/leads out of measurements

3. Self Test (test fixturing/leads loopback testing to ensure good access to DUT)

4. Gold Unit/Prototype

5. reliability/repeatability (valid tests must be repeatable)

5.1. Retest Correlation

5.1.1. Analyze multiple runs for reliability

6. Accuracy of test

6.1. TE 4:1 accuracy ratio (industry standard but should be defined in the test requirements)

7. Test Methodology (described in Test Requirements)

7.1. inputs to DUT correct and within accuracy requirements
