Question: For a UTRA Repeater, what determines the applicability of the Relative Code Domain Error requirement?
Option 1: The type of modulation used (e.g., only applicable for Repeaters supporting 64QAM modulated codes)
Option 2: The spreading factor of the active code channels in the composite reference waveform
Option 3: The measurement interval duration (e.g., frame length)
Option 4: The number of active code channels in the composite reference waveform
Explanation: The Relative Code Domain Error requirement is specifically applicable based on the modulation type used by the Repeater, making it relevant only for those supporting 64QAM (64-Quadrature Amplitude Modulation) modulated codes. This highlights the importance of modulation schemes in determining conformance testing requirements for UTRA Repeaters, ensuring they meet standards for signal quality and integrity under specific operational conditions.
