Rohde & Schwarz has introduced a line of compact FM transmitters — SR8000 and NR8200 — designed to wed high quality analog networks with digital reliability.
NR8200 Series transmitters are available for powers of 2.5 kW to 40 kW. Two single transmitters of up to 5 kW each can be accommodated in a 19-inch rack. The 30 kW transmitter fits in 2 racks.
Exciter standby, (n+1) standby, passive standby and active dual-output stage with manual or automatic switchover can be implemented for the NR8200 line. Transmitters already in the network can be integrated in a (n+1) redundancy system.
SR8000 Series transmitters are rated for output powers from 100 W to 2.5 kW. All functions are integrated in a single transmitter and occupy a maximum of 8 rackunits. Single-frequency network operation is possible. Passive standby and (n+1) standby systems containing up to eight main transmitters are available as a standby system.
The transmitters are air-cooled. Transmitter and amplifier parameters required for diagnostics can be retrieved locally or remotely via Internet protocol and standard software.
