brief description

the r&s®atcmc16 is a multicoupler specifically designed for atc receivers from rohde & schwarz.

the r&s®atcmc16 saves space while optimally supporting conventional atc system installations by means of up to 16 receivers operated in parallel on one antenna.

alternatively, the r&s®atcmc8 multicoupler features simultaneous signal distribution to eight receivers.

the multicoupler's integrated, steep-sided filters reliably suppress interference from high-power vhf fm and tv signals.

features & benefits

suppression of adjacent high-power signals

the integrated bandpass filtering of the r&s®atcmc16 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. to offer optimized filtering for any application, the r&s®atcmc16 is available as either a vhf or a uhf model. in addition, rohde & schwarz offers various options with different filter characteristics for the r&s®atcmc16.

available as 1-to-8 or 1-to-16 model

in atc, the parallel operation of eight or 16 receivers on one antenna each is very common. the r&s®atcmc multicoupler family can easily handle this challenge and is therefore available as either an 8- or 16-port model. to prevent the connected receivers from affecting each other (e.g. due to local oscillators and synthesizers), both models feature high port-to-port isolation.

integrated automatic emergency power switchover

the r&s®atcmc16 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®atcmc16 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®atcmc multicoupler family offers impressive capabilities for the remote monitoring of the internal operating state. if a malfunction occurs, the r&s®atcmc16 immediately switches the floating contacts of a relay in order to indicate the modified operating state. all internal supply voltages of the amplifiers are monitored. in conjunction with r&s®series 4200 radios, this alarm contact offers the capability to automatically report the operating state of the r&s®atcmc16 to the user.
