Question: What is the primary purpose of measuring Transmit Intermodulation Performance in a User Equipment (UE: User Equipment) transmitter, as defined in 3GPP specifications?
Option 1: To assess the UE's ability to suppress unwanted signals generated by non-linear elements when exposed to both desired and interfering signals.
Option 2: To evaluate the UE's receiver sensitivity in the presence of multiple carriers.
Option 3: To determine the maximum transmit power of the UE on assigned carriers.
Option 4: To test the UE's handover capability between different base stations.
Explanation: The correct answer, Option 1, highlights the core objective of measuring Transmit Intermodulation Performance, which is to gauge how well a UE's transmitter can prevent the creation of unwanted signals (intermodulation products) by its non-linear components when it is transmitting the desired signal and also receiving an interfering signal. This is crucial for maintaining signal purity and overall network performance, especially in scenarios involving multiple carriers or frequencies, such as HSDPA and Dual Cell E-DCH configurations mentioned in the context.
