Question: In UTRA Repeater conformance testing, as per 3GPP specifications, what is the primary purpose of adjusting the signal level to the equivalent level for obtaining the nominal output power declared by the manufacturer during initial test set-up?
Option 1: To ensure the Repeater operates at minimum gain for sensitivity testing.
Option 2: To validate the manufacturer's declared noise floor performance.
Option 3: To provide a standardized baseline for measuring the Repeater's Error Vector Magnitude (EVM) under optimal operating conditions.
Option 4: To test the Repeater's ability to handle maximum input power without distortion.
Explanation: Adjusting the signal level to obtain the nominal output power declared by the manufacturer ensures that the EVM measurement, which is a key indicator of signal quality, is conducted under optimal (full gain) and standardized conditions. This allows for an accurate assessment of the Repeater's performance in terms of signal integrity and fidelity, as specified in 3GPP conformance testing protocols.
