Hi All I have a question about AP5131 Antenna Diversity. What do Primary Only, Secondary Only and Full Diversity mean ? From AP's manual, the description of Primary Only is "Enable only the primary" and so does the description for Secondary Only. We use a spectrum analyzer to test the output signal from AP5131. We found that if we set to "Primary Only", the spectrum analyzer can still meansure signal from the secondary port. We use direct cable to connect the Secondary port to the RF input port on the spectrum analyzer. Regards Antony
