Innovator® CX Solid State Transmitter This advanced transmitter line uses our frequency agile exciter and LDMOS transistors for broadband operation across the entire operating band. This allows multi-station owners and networks to minimize spare parts stock, and also enables simple and inexpensive channel changes. The Innovator CX is available as a transmitter, translator/ transposer or low-delay echo-canceling gap-filler/repeater.Axcera’s Innovator CX series is a line of The platform supports most any current digital standard, including ATSC, ATSC Mobile DTV, DVB-T/T2/H/SH, feature rich, economical and compact ISDB-T/Tb, DAB, T-DMB, CMMB (STiMi), MediaFLO™ and VHF & UHF television transmitters and more. Remote monitoring and control is easily achieved through the available Web browser or SNMP interface. gap fillers that offer a high level of Like all Axcera products, the Innovator CX is manufactured performance and reliability. and supported by our world-class organization under strict ISO9001:2000 quality control.The Innovator CX is fully contained in a Flexible Design and Broad Power Range All aspects of the Innovator CX design, from frequency single 3RU chassis for power levels range to multi-standard compatibility, reflect Axcera’s long-term commitment to broadcasters worldwide. Theup to 125W UHF and 200W VHF, and can Innovator CX offers a wide range of modulator and receiverachieve up to 1800W ATSC, 1600W DVB options and power levels, making the Innovator CX perfect for use as a main transmitter, as a gap filler or translator, or and 3900W analog with additional for building very efficient single frequency networks (SFNs) using a common transmitter platform. The Innovator CX compact, higher-power amplifiers. allows broadcasters to lower both acquisition and operating costs, especially for multi-transmitter operators. To maximize reliability, the control system, exciter and low power amplifiers are completely contained in a single 3RU rack-mount chassis for most configurations. All high power amplifier stages use parallel transistors to ensure excellent availability. This simple design enhances reliability by reducing component parts count and minimizing harnessing and single point paths, resulting in high MTBF performance. At the same time, the simplicity of the design ensures easy installation and maintenance. For outdoor installations, the Innovator CX can be integrated into a self-contained, climate-controlled outdoor enclosure, including network management systems, satellite and synchronization receive equipment, IP input for interface
