Keysight Pass / Fail Decision Rules

Application Notes

Measurement Decision Risk Overview

In a pass/fail test application, the test system makes a measurement and then compares the result to a published specification. This repeated process ensures the device under test (DUT) conforms to its specified requirements. As much as we would like to trust the accuracy of the pass/fail measurement result, there are always two possible outcomes:

  1. A correct pass/fail decision
  2. An incorrect pass/fail decision

a. Called “false accept”, or “false reject”
