Question: In conformance testing for UE/MS OTA antenna performance (GSM), what is the uncertainty for a single measurement when targeting a Block Error Rate (BLER) of 10%±2% with 20,000 tested bits?
Option 1: 0.13 dB
Option 2: 0.46 dB
Option 3: 0.20 dB
Option 4: 1.00 dB
Explanation: This question assesses understanding of measurement uncertainty in the context of antenna performance testing for User Equipment (UE)/Mobile Stations (MS) over the air (OTA), specifically within GSM parameters. The correct answer, 0.46 dB, directly corresponds to the specified conditions (BLER target of 10%±2% with 20,000 tested bits), highlighting the importance of precise measurement uncertainty in ensuring reliable antenna performance conformance testing. Incorrect options (0.13 dB, 0.20 dB, and 1.00 dB) are plausible but do not match the given test conditions, requiring the test-taker to carefully consider the relationship between BLER targets, tested bits, and measurement uncertainty. **(UE: User Equipment, MS: Mobile Station, OTA: Over The Air, BLER: Block Error Rate)**
