Question: In a reverberation chamber method for testing UE/MS OTA antenna performance, what is the primary purpose of adjusting the base station simulator's output power during BER (Bit Error Rate) measurements?
Option 1: To achieve a target BER value of 2.00% or 0.2%, indicating optimal transmission quality for TRS (Total Radiated Sensitivity) calculation.
Option 2: To simulate various environmental conditions such as urban, rural, and indoor scenarios.
Option 3: To test the UE's/MS's ability to handle different modulation schemes.
Option 4: To evaluate the impact of antenna orientation on signal reception.
Explanation: Adjusting the base station simulator's output power is done to find the lowest output power yielding a BER value of 2.00% or 0.2%, crucial for accurately calculating the Total Radiated Sensitivity (TRS) of the UE/MS, assessing its antenna's sensitivity and overall radio communication capability.
