DT300B/DT400B Series
Low Power VHF DTV Transmitters/Translators 350W - 2.1kW
These low power VHF DTV transmitters and translators deliver high quality and per-
formance in a compact and economical package - perfect for broadcasters wishing
to get a DTV signal on the air quickly. The time-proven Axcera DT1C modulator or
optional DT2B adaptive modulator, generates the ATSC-compliant 8VSB IF signal,
which feeds the companion upconverter. The upconverter provides a pre-correct-
ed output directly to the high-gain final power amplifier modules (three PAs in the
1000W unit). The entire package is housed in a single 19 inch rack-mount cabinet.
Designed for high reliability and unattended operation, each power amplifier
utilizes a parallel amplifier design with a high level of protection circuitry. Features
such as VSWR cutback, overdrive protection and over-temperature protection ensure
on-air reliability. Convenient system monitoring is achieved through front panel
samples, status indicators and metering, most of which are remote controllable.
