X-QAM QUAD Четырехканальный ковертор DVB-S/S2 (QPSK/8PSK)→QAM

Раздел: Модуля Х серии

Описание
Технические характеристики

- транскодирование 4-х DVB-S/S2-модулированных SATсигналов в 4 QAM выходных потока двумя независимыми парами соседних каналов

- использование технологии Direct Digital позволяет достичь высочайших выходных параметров, такие как: MER typ. 45 dB

- возможна трансмодуляция DVB-S2/HDTV в QAM256.

- обработка MPEG потока: настройка скорости потока, удаление нежелательных сервисов, PCR-correction, PID-filter (pass and drop service filter), NIT-generation
