Question: In a Multi-Standard Radio (MSR) Base Station (BS) Electromagnetic Compatibility (EMC) test, as per 3GPP specifications, what is the governing standard for the test method to assess susceptibility to surge voltages?
Option 1: IEC 61000-4-2 (Electrical Fast Transient/Burst Immunity Test)
Option 2: IEC 61000-4-5 (Surge Immunity Test)
Option 3: IEC 61000-4-3 (Radiated, Radio-Frequency, Electromagnetic Field Immunity Test)
Option 4: IEC 61000-4-6 (Conducted Disturbances, Induced by Radio-Frequency Fields)
Explanation: The correct answer is IEC 61000-4-5 because the question specifically mentions the test method for surge voltages in the context of MSR BS EMC testing. IEC 61000-4-5 is the standard that deals with Surge Immunity Tests, which are crucial for assessing how well equipment withstands sudden, brief overvoltage conditions (surges). This aligns with the requirement mentioned in the provided context, ensuring the equipment’s resilience against such electrical disturbances.
