Question: In conformance testing for UE/MS OTA antenna performance in WCDMA, using a BER target of 10%±2% with 20,000 tested bits, what is the uncertainty expected for a single measurement?
Option 1: 0.05 dB
Option 2: 0.19 dB
Option 3: 0.46 dB
Option 4: 1.00 dB
Explanation: The correct answer is based on the relationship between Bit Error Rate (BER) targets, the number of tested bits, and the resulting measurement uncertainty in WCDMA conformance testing for UE/MS OTA antenna performance. A higher BER target with a fixed number of tested bits leads to greater uncertainty. With a 10% BER target and 20,000 tested bits, an uncertainty of 0.46 dB is expected, reflecting the balance between test stringency and measurement reliability.
