Platinum-i™ Series

Solid-State VHF ATSC DTV Transmitter

The Platinum-i™ series of solid-state VHF ATSC DTV transmitters is the ultimate solution for digital television transmission, offering the highest levels of performance, reliability and functionality. Employing the same field-proven technologies that have made the Harris® Platinum Series® transmitters a world standard leader, Platinum-i transmitters incorporate the versatile and cost-effective Harris eCDi® integrated control system and remote interface.

A highly intuitive, color LCD graphical user interface (GUI) provides detailed information, system control and in-depth diagnostics locally. The standard web GUI allows remote users to access full control and monitoring capabilities at virtually any location using a standard PC and web browser. A more extensive eCDi software package is optionally available that provides more in-depth ATSC measurement capability.

It is easy to upgrade any existing Platinum Series analog or digital transmitter to reap the benefits of unsurpassed monitoring and control capability. With the upgrade, the transmitters will be able to provide IP-based control and monitoring by using the Harris eCDi remote monitoring system, either tied to the station LAN or directly to the Internet.

Features

Each Platinum-i transmitter includes market-leading features:

Apex M2X™ multimedia exciter, allowing easy migration between standards
Real-Time Adaptive Correction (RTAC™), providing continuous automatic correction for optimum performance at all times
Built-in eCDi control system with color touchscreen, providing extensive local and remote control and monitoring capabilities
Field-proven, ultra-reliable Platinum Series amplifier modules for unsurpassed system dependability
Positive-pressure air cooling system with patented techniques, ensuring the lowest FET junction temperatures and highest MTBF
On-air replaceable modules and a distributed control architecture, allowing on-air servicing and increased system availability
