Question: In testing the electromagnetic compatibility (EMC) of a Base Station (BS) according to 3GPP specifications, how should the Protective Earth (PE) conductor be terminated in accordance with CISPR standards for accurate measurement?
Option 1: Open termination to prevent any interference
Option 2: Short circuit to ensure safety
Option 3: 50 Ω/50 μH common mode RF impedance as per CISPR guidelines
Option 4: Directly connected to the mains via a separate AMN
Explanation: To accurately measure EMC in accordance with CISPR standards (specifically CISPR 16-1), the Protective Earth (PE) conductor should be terminated with a 50 Ω/50 μH common mode RF impedance. This setup is crucial for minimizing external influences and ensuring the reliability of the test results, reflecting real-world electromagnetic compatibility scenarios for telecom equipment like Base Stations.
