R&S®ASDU02 Antenna Signal ­Distribution Unit Active multicoupler for antenna signal distribution

R&S®ASDU02 ­Antenna Signal ­Distribution Unit At a glance High port-to-port isolation The modules feature high port-to-port isolation to prevent the connected receivers from affecting each other, e.g. via local oscillators or synthesizers. BITE option for device monitoring The BITE option allows the hardware status of the two multicouplers to be monitored. The internal voltages of the modules and the power supply unit are also measured. As an additional highlight, the operating points of the broadband amplifiers are monitored. The R&S®ASDU02 is an active multicoupler for distributing signals...
