Question: In 3GPP conformance testing for TDD Base Stations, why is chip clock deviation not separately processed, despite being a potential 'deviation' type parameter?
Option 1: Because chip clock deviations have no impact on system performance in TDD modes.
Option 2: Due to the direct relationship between chip clock and RF frequency, as stated in core specifications, only RF frequency needs to be processed.
Option 3: Since modulation schemes in the system depend on absolute chip clock timing, it's inherently covered by RF phase variation.
Option 4: Chip clock deviations are irrelevant to Node B testing but crucial for UE Timing Advance error description.
Explanation: The correct answer is based on the understanding that, according to the 3GPP core specifications, chip clock and RF frequency are interlinked. This means that by processing RF frequency, any deviations in chip clock (which would affect or be reflected in RF frequency) are indirectly accounted for, making separate processing of chip clock deviation unnecessary. This highlights the importance of understanding specification interdependencies in telecom testing.
