Question: In conformance testing for User Equipment (UE) as per 3GPP standards, what is the maximum tolerance allowed for setting downlink signal levels by the Signal Simulator (SS) from the defined levels?
Option 1: +/-1dB
Option 2: +/-2dB
Option 3: +/-3dB
Option 4: +/-5dB
Explanation: The correct answer is Option 3 because, according to the specifications for conformance testing of User Equipment (UE), the Signal Simulator (SS) must be capable of setting downlink signal levels within a maximum tolerance of +/-3dB from the defined default signal levels or those specifically outlined in a test case. This precision is crucial for accurate and reliable testing outcomes, ensuring the UE performs as expected under various signal strength conditions.
