Question: What is the allowable deviation in gain measurement for a Repeater (EUT) during electromagnetic compatibility (EMC) testing, to ensure it operates as intended post-exposure?
Option 1: ± 0.5 dB
Option 2: ± 3 dB
Option 3: ± 1 dB
Option 4: ± 2 dB
Explanation: The correct answer is ± 1 dB because, according to the specified performance criteria for continuous phenomena in repeater EMC testing, the gain of the Equipment Under Test (EUT) should not deviate by more than ± 1 dB from its pre-test measurement. This strict tolerance ensures that the repeater maintains its intended functionality and performance after exposure to electromagnetic interference, safeguarding user control functions and stored data integrity.
