Question: For a Satellite Access Node (SAN) without polarization diversity, what is the maximum number of demodulation branches that can be tested for radiated performance requirements?
Option 1: 2 demodulation branches (e.g., 2RX test setup)
Option 2: 1 demodulation branch (e.g., 1RX test setup)
Option 3: 4 demodulation branches (e.g., 4RX test setup)
Option 4: The number of demodulation branches is not limited for testing
Explanation: According to the specifications, if a Satellite Access Node (SAN) does not utilize polarization diversity, the radiated performance requirements can only be tested for a single demodulation branch, which corresponds to a 1RX test setup. This ensures that the testing accurately reflects the SAN's capability without polarization diversity.
