R&S®NW8200 VHF Transmitter Family
Air-cooled medium-power transmitters for digital TV
Design concept
Standardized design for analog and digital TV
The new air-cooled R&S® NM/NW8200 family of transmitters has been designed for the analog TV standards (B/G, D/K, M/N, I), color coding standards (SECAM, PAL, NTSC) and sound coding standards (FM mono, dual-sound/stereo IRT and NICAM) as well as for the digital TV standards (DVB-T/-H, ATSC). LDMOS transistor-based amplifiers ensure high output power while requiring only minimum space. All components are fully broadband from 170 MHz to 250 MHz (VHF band III) for both the analog and digital standards. For analog TV (combined), available output power ranges from 750 W to 3 kW, for digital TV from 330 W to 2 kW (DVB-T/-H) and 500 W to 2 kW (ATSC).
The transmitters include the following components:
- Exciter
- Power amplifier(s)
- Transmitter control unit
- Transmitter rack with cooling system
The new family of VHF Transmitters R&S® NM/NW8200 relies on a design concept common to all Rohde & Schwarz sound and TV transmitters of the R&S® Nx8000 family. This means that the transmitter control unit and the bus system for internal and external communication are identical throughout.
