Question: In a Base Station (BS) conformance test for TDD as per 3GPP specifications, if the measured Bit Error Rate (BER) exceeds the specified limit of 0.001, what is the implication regarding Test Tolerance?
Option 1: The Test Tolerance is automatically set to zero.
Option 2: The Minimum Requirement for BER has been met without any relaxation.
Option 3: A non-zero Test Tolerance has been applied, indicating a relaxation of the Minimum Requirement.
Option 4: The test is invalid and must be repeated with adjusted settings.
Explanation: Exceeding the specified BER limit in a conformance test suggests that the actual performance deviates from the expected minimum requirement. Given this context, if the Test Requirement (e.g., the measured BER of 0.001) differs from what is considered acceptable due to such deviations, it implies that some form of tolerance or relaxation has been applied to the Minimum Requirement, making the Test Tolerance non-zero. This ensures the test's practicality while still maintaining a standard.
