Question: In a multi-band capable Base Station (BS) setup, how should the non-tested antenna connector be handled during single-band or multi-band testing, if the BS has separate antenna connectors?
Option 1: Left open to allow for external monitoring
Option 2: Connected to a secondary test equipment for simultaneous testing
Option 3: Terminated to prevent interference
Option 4: Switched to a different frequency band for concurrent testing
Explanation: In a multi-band capable BS with separate antenna connectors, terminating the non-tested antenna connector is crucial to prevent potential interference that could affect the accuracy of the test results. This ensures the testing of one band does not inadvertently influence the signals of another, thus maintaining the integrity of the single-band or multi-band tests being conducted.
