suppression of adjacent high-power signals
the r&s®admc8´s integrated bandpass filtering considerably improves the reception conditions for the connected receivers. adjacent signals such as high-power fm signals in the vhf band or tv signals in the uhf band are suppressed. the r&s®admc8 is available as a uhf model. the r&s®admc-b1 option is offered for cases where customized filters are needed.
in atc, parallel operation of eight receivers on one antenna is very common which is why the r&s®admc8 multicoupler has eight ports. to prevent the connected receivers from affecting each other (e.g. due to local oscillators or synthesizers), the multicoupler features high port-to-port isolation.
integrated automatic emergency power
the r&s®admc8 is ideal for operation with either ac or dc power. the integrated electronic switchover mechanism automatically detects interruptions in the ac power supply and immediately switches to the dc supply without any signal interruption. the emergency power supply systems with 24 v dc voltage that are common in atc can be used.
reliable protection against large signals
the integrated protective circuits at the rf input protect the r&s®admc8 against large signals and reliably prevent damage to the connected receivers.
remote monitoring through floating alarm contact
featuring an integrated alarm contact as standard, the r&s®admc8 offers impressive capabilities for remote monitoring of the internal operating state. if a malfunction occurs, the r&s®admc8 immediately switches the floating contacts of a relay to indicate the modified operating state. all internal supply voltages of the amplifiers are monitored. in conjunction with r&s®series4200 and r&s®series4400 radios, this alarm contact offers the capability to automatically report the operating state of the r&s®admc8 to the user.
