Question: In a Terminal conformance test for Radio transmission and reception (TDD), what triggers an immediate Fail decision for the Device Under Test (DUT), based on error ratios calculated from delays?
Option 1: ER0 (Error Ratio excluding artificial error) is on or above the early fail limit.
Option 2: ER1 (Error Ratio including artificial error) is below the early pass limit.
Option 3: The total number of bad delays exceeds the total number of all delays.
Option 4: The confidence level (1-F) for a correct decision probability cannot be achieved within the test duration.
Explanation: According to pass/fail decision rules, an immediate fail decision for the DUT is triggered when ER0, excluding artificial error at the beginning of the test, is on or above the defined early fail limit, indicating the device's performance has fallen below the acceptable threshold.
