Question: In E-UTRA and EPC conformance testing for User Equipment (UE), what is a commonality across the test equipment for RF, EMC, and Signalling Conformance Testing, as per generic requirements?
Option 1: The number of Tx antennas used must be the same across all tests within each category.
Option 2: The test equipment supplier must provide a single, unified platform for all three testing categories.
Option 3: Each testing category (RF, EMC, Signalling) requires unique and separate test equipment with no shared requirements.
Option 4: The operating frequency range of the test equipment varies between RF, EMC, and Signalling Conformance Testing.
Explanation: According to generic requirements, a key commonality is that the test equipment must use the same number of Tx (Transmission) antennas for all parts of the tests, ensuring consistency across different testing scenarios for reliable and comparable results.
