Question: In UTRA Repeater Conformance Testing, after setting the signal generator to produce maximum output power at maximum gain (Step 2), what is the next step's primary purpose regarding the signal's power level?
Option 1: To decrease the power by 5 dB for interference assessment
Option 2: To maintain the current power level for sensitivity testing
Option 3: To switch to a different test model for diversity evaluation
Option 4: To increase the power by 10 dB for overdrive margin testing
Explanation: The correct answer, increasing the power by 10 dB (Option 4), aligns with Step 4 of the procedure. This step aims to test the repeater's performance under conditions exceeding its specified maximum output power at maximum gain, essentially evaluating its overdrive margin or how it handles increased signal strength beyond its rated capacity. This is crucial for understanding how the device will behave in real-world scenarios where input signals may fluctuate significantly.
