Question: In conformance testing for UE/MS Over The Air (OTA) antenna performance using a base station simulator, how should the uncertainty of the transmitter device's absolute level be handled if not otherwise informed?
Option 1: It is assumed as systematic and calibrated out in all measurement stages.
Option 2: Calculated from manufacturer’s data with a triangular distribution for conservatism.
Option 3: Calculated from manufacturer’s data in logs with a rectangular distribution.
Option 4: Ignored, as non-linearity of the device is the dominant factor.
Explanation: The correct approach to handling uncertainty in the absolute level of the transmitter device (e.g., a BS Simulator) in OTA antenna performance testing involves utilizing manufacturer-provided data. Specifically, this uncertainty is best represented with a rectangular distribution when calculated from these logs, unless alternative guidance is provided.
