Question: In the context of Electromagnetic Compatibility (EMC) for NR Repeaters, where must surge tests be performed in addition to AC mains power input ports?
Option 1: Only on a representative configuration of the repeater's radio equipment
Option 2: Exclusively on the associated ancillary equipment's interfaces
Option 3: Additionally on telecommunication ports
Option 4: Solely on the combination of radio and ancillary equipment's power supply
Explanation: This is correct because, according to EMC testing standards for NR Repeaters, ensuring resilience against surges is crucial not just at the point of power entry (AC mains) but also where data or signals are exchanged (telecommunication ports), thus safeguarding both power and signal integrity. This comprehensive approach helps in maintaining the overall reliability and performance of the repeater system within a telecom network.
