 The DT820A low power DTV transmitter delivers high quality and performance in a compact and economical package - perfect for broadcasters wishing to get a DTV signal on the air quickly. The field-proven DT1B modula-tor generates the ATSC-compliant 8VSB IF signal. The modulator feeds the exciter and amplifier which are housed in a single 14” high rack mount tray assembly with a flip out panel for easy access to the internal circuitry. Designed for high reliability and unattended operation, this transmitter utilizes a parallel amplifier design with a high level of protection circuitry. Features such as VSWR cutback, overdrive protection, over-temperature protec-tion, and an output circulator ensure on-air reliability. Convenient system monitoring is achieved through front panel samples, status indicators and metering, most of which are remote controllable. |
