Question: In conformance testing for UE/MS OTA antenna performance, what is the primary purpose of utilizing a signal generator in place of the Device Under Test (DUT) during calibration?
Option 1: To amplify the power level for enhanced antenna sensitivity
Option 2: To provide a known power level to the calibration antenna for uncertainty assessment
Option 3: To simulate various environmental conditions for robustness testing
Option 4: To bypass the need for manufacturer's data in logs for distribution analysis
Explanation: The signal generator's role is to feed the calibration antenna with a known power level, crucial for assessing and calculating the uncertainty of the absolute output level, essential for accurate conformance testing.
