Standardized design for analog and digital TV
The new air-cooled R&S®NH8300/R&S®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, DVB-T2, DVB-H, ISDB-T, ISDB-TB,
MediaFLO™, ATSC, ATSC Mobile
DTV). 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.
