R&S^®SR8000 Family of VHF FM Transmitters

At a glance

The air-cooled R&S^®SR8000 generation of FM transmitters covers a power range from 100 W to 2.5 kW.

The transmitters include the following components:

• Exciter based on the R&S^®SU800
• Power amplifier
• Housing with integrated cooling
• Power supply
• Integrated transmitter control unit

All transmitters feature outstanding technical parameters, an optimum cost/benefit ratio, extremely high reliability plus ease of servicing. They contain the engineering of the digital state-of-the-art R&S^®SU800 exciter and include an integrated AES/EBU interface.

The air-cooled 19" units are extremely compact. The 100 W transmitter occupies two height units, the 1000 W transmitter four height units, and the 2.5 kW transmitter only eight height units. The 2.5 kW transmitter consists of two modules. The first module contains the exciter functions, an amplifier with an integrated splitter and a power supply. The second module contains the second amplifier, the combiner, the absorber and a second power supply.

The transmitter control unit handles internal and external communications, including all control functions, and displays the transmitter‘s current status in various languages on a display. All transmitter and amplifier parameters required for diagnostics can be retrieved locally as well as remotely via standard (IP) protocol and standard software (web browser, SNMP option). In addition, an integrated parallel remote-control interface for message signaling and commands is available.

Both (n+1) standby and passive standby systems can be implemented.

The transmitters comply with the R & TTE Directive 1999/5/EC and meet the following standards: EN 60215 for protection of personnel, EN 301489-1 and EN 301489-11 for EMC, EN 302018-1 and EN 302018-2 for RF requirements and ITU-R B.S450-3 for stereo emissions.
