Question: In Japan, for regulatory testing of Terminal conformance specification (Radio transmission and reception - FDD), what approach may be applied provisionally regarding shared risk against core specification values until regulatory updates?
Option 1: Strict adherence to non-zero test tolerances as per international standards.
Option 2: Application of a fixed, reduced test tolerance value across all specifications.
Option 3: Exemption from testing for Spectrum Emission Mask requirements.
Option 4: Shared risk with a test tolerance of zero, pending reflection of non-zero tolerance principles in Japanese regulations.
Explanation: This is the correct approach as per the provided context. It highlights a provisional measure for regulatory testing in Japan, allowing shared risk against core specification values with a test tolerance of zero. This is specifically permitted until Japan's regulations incorporate the principle of non-zero test tolerances used in the referenced document. This approach balances compliance with the anticipation of future regulatory alignment.
