The UBS Universal Modulator Series utilizes the innovative UBS Universal Waveform engine, supporting all world standards for mobile and terrestrial digital broadcasts. Using the latest technology, UBS has developed a direct conversion process that allows the Universal Modulator to provide an RF output from 47 MHz to 946 MHz with superior shoulders and MER. The Universal Modulator can be configured to support one, two or all the waveforms listed above. The user can easily switch from one waveform to another through software selection. UBS’ modulators can also be upgraded in the field as standards evolve.
This open architecture design enables carriers to take advantage of a proven, robust platform, while designing networks to meet current and future broadcast standards. This series incorporates all of UBS high performance signal processing stages including integrated linear and non-linear pre-correctors.
Full remote management and control as well as remote firmware and waveform upgrades are provided.
