Question: In a conformance test for Radio transmission and reception (FDD), if the minimum test time is less than the time required to reach the target number of error events, how is the Device Under Test (DUT) passed or failed based on Bit Error Rate (BER)?
Option 1: The DUT passes if BER0 (excluding artificial error) is below the early pass limit, and fails if BER1 (including artificial error) is above the early fail limit.
Option 2: The DUT passes if BER1 (including artificial error) is below the early pass limit, and fails if BER0 (excluding artificial error) is above the early fail limit.
Option 3: The DUT passes if both BER0 and BER1 are below their respective early pass limits, and fails if either is above its early fail limit.
Option 4: The test continues without a pass/fail decision until the minimum test time is reached, regardless of BER values.
Explanation: According to specified pass/fail decision rules for when the minimum test time is less than the time needed for the target number of error events, the DUT is passed if BER1 (including an artificial error at the beginning of the test) is below the early pass limit. Conversely, it fails if BER0 (excluding the artificial error) is above the early fail limit. This approach ensures a balance between the impact of initial conditions and ongoing performance.
