Question: What is the primary reason for having tighter test requirements for Receiver Spurious Emissions in Receive-Only-Operation compared to RX-TX-Operation in a UE (User Equipment)?
Option 1: To account for the generally longer duration of Receive-Only-Operation, which increases potential interference impact.
Option 2: Due to the higher transmission power levels used during Receive-Only-Operation.
Option 3: Because Receiver Spurious Emissions are inherently more disruptive to other systems than TX Spurious Emissions.
Option 4: As a result of the shorter switching time between receive and transmit modes in RX-TX-Operation.
Explanation: The correct answer highlights the key reason for stricter test requirements: the prolonged duration of Receive-Only-Operation increases the potential for interference, necessitating tighter limits to protect both the UE's own system and other systems from spurious emissions.
