R&S®NV8300 UHF Transmitter Family
Air-cooled medium-power transmitters for digital TV
Standardized design for analog and digital TV
The new air-cooled R&S®NH/NV8300 family of transmitters has been designed for analog TV standards (B/G, 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 digital TV standards (DVB‑T/‑H, ATSC, MediaFLOTM, ISDB-T, AVSB, ISDBTB). LDMOS transistor-based amplifiers ensure high output power while requiring only minimum space.
All components are fully broadband from 470 MHz to 862 MHz (UHF bands IV/V) for both the analog and digital standards. The available output power ranges from 750 W to 2.8 kW for analog TV (combined), and from 300 W to 1.8 kW (DVB-T/-H, MediaFLOTM, ISDB-T, ISDBTB) as well as 450 W to 1.8 kW (ATSC, AVSB) for digital TV.
The transmitters include the following components:
- Exciter
- Power amplifier(s)
- Transmitter control unit
- Transmitter rack with cooling system
The new R&S®NH/NV8300 family of UHF transmitters is based on a design concept that is 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 communications are identical throughout.
