Question: What is the maximum allowable change in gain for a Repeater (EUT) after each exposure to transient phenomena, as well as after the entire test series, to ensure it operates as intended?
Option 1: ± 0.5 dB
Option 2: ± 1 dB
Option 3: ± 2 dB
Option 4: ± 3 dB
Explanation: The correct answer is ± 1 dB because, according to the performance criteria for transient phenomena in repeaters, after each exposure and at the conclusion of the total test, the gain of the Equipment Under Test (EUT) - in this case, a repeater - shall not have changed by more than ± 1 dB. This ensures that the device continues to operate as intended without significant degradation in performance, maintaining user control functions and stored data integrity.
