Question: In 3GPP Base Station conformance testing for FDD, what triggers the conclusion of a test, prompting the application of pass/fail decision rules?
Option 1: Expiration of the minimum test time or occurrence of an early pass/fail event
Option 2: Completion of a fixed number of samples tested
Option 3: Achievement of a predefined bit error or block error rate threshold
Option 4: Manual intervention by the test administrator
Explanation: According to the specified test method for Base Station conformance testing, a test is stopped (and thus concluded) when either the minimum required test time has elapsed or an early pass/fail event occurs. This stop criterion directly precedes the application of pass/fail decision rules, highlighting its critical role in determining the outcome of the test.
