OVERVIEW

GatesAir’s OnePower medium power systems by ONEtastic are housed in extremely compact rack-mount configurations, including 2 power supplies.  The ONEPower medium power delivers up to 2,500W average DTV output power, or up to 4,000W peak sync with analog modulation.

The system comprises 1 or 2 OneDriver exciter/s (1RU each) and an RF amplifier (2 or 3 RU), to make a complete DVB-T/H/T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC-1, PAL or NTSC transmitter, with real-time adaptive pre-correction circuits, a built-in GPS/GLONASS receiver for accurate synchronization and SFN timing, and multiple input interfaces (Satellite Receiver, ASI, ETI, EDI, Gigabit Ethernet or RF).  This allows it to be configured as a terrestrial or satellite-fed transmitter, or a transposer.

OnePower’s PA stage embeds two hot-swappable power supply units, as well as a built-in ASI and RF changeover, allowing a dual-drive configuration, ensuring maximum redundancy while removing the need for an additional external switchover unit.
