Key Facts

  • 300 W to 1.8 kW output power for DVB-T, DVB-T2, DVB-H, ISDB-T, ISDB-TB, MediaFLO
  • 450 W to 1.8 kW output power for ATSC, ATSC Mobile DTV
  • Frequency range 470 MHz to 862 MHz

Brief Description

  • Standardized design for analog and digital TV

    LDMOS transistorbased 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 analogand 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, DVB-T2, DVB-H, ISDB-T, ISDB‑TB, MediaFLO) as well as from 450 W to 1.8 kW (ATSC, ATSC Mobile DTV) for digital TV.

    The transmitters include the following components:

    • Exciter
    • Power amplifier(s)
    • Transmitter control unit
    • Transmitter rack with cooling system

    The R&S®NH8300/R&S®NV8300 family of UHF transmittersis 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.

Features & Benefits

  • R&S®Sx800 multistandard TV exciter for digital or analog signal processing
    • The exciter can be converted from analog to digital at any time
    • Various standby configurations
    • Easy servicing due to modular design and plug-ins
    • For operation in single-frequency networks, a MIP decoder enables automatic delay compensation
    • Digital signal processing provides maximum stability and easy precorrection
  • Air-cooled broadband R&S®VH8300A1 power amplifier
    • For analog and digital signals without requiring any adjustment
    • With innovative amplifier controller, which is used for all sound and TV transmitters of the R&S®Nx8000 family
    • Output power control makes for long life for the individual transistors
    • Each amplifier module is self-monitoring and self-protecting
    • Based on LDMOS technology
    • All amplifier modules can easily be replaced during operation
  • Innovative R&S®NetCCU®800 transmitter control unit
    • The R&S®NetCCU®800 clearly shows the current status of the transmitter system on a color display
    • Transmitter remote control and monitoring via SNMP and/or HTTP interface
    • All parameters required for diagnostics can be retrieved locally as well as remotely
    • In-depth diagnostics through new bus system
    • Only two height units
  • Transmitter rack with integrated cooling
    • Same 19" rack (depth 800 mm) used for all power classes
    • One rack accommodates up to six amplifier modules
    • Contains two built-in fans that operate in active standby
    • Various air ducting configurations
    • Effective cooling with a minimum amount of air considerably reduces the cooling system's power consumption and noise generation
