C8U-L  

The Commander 8® Upconverter (model C8U) is the next generation headend Upconverter which builds on the award winning success of the Commander 6® Upconverter. 2 frequency agile models, the C8U-L (50 to 600 MHz) and the C8U-H (550 to 1000 MHz), cover all current and future broadband frequency requirements up to 1 GHz, with a convenient 50 MHz frequency overlap between Models The C8U consists of dual independent Upconverters in a reliable single rack unit (1RU) package, avoiding thermal and mating problems while providing space efficiency. A bright, wide two-line vacuum fluorescent display (VFD) provides access to all upconverter controls and is accessed via a convenient menu system. Front panel access to independent RF and IF test points is provided. Easy rear panel fuse access is also provided. Each independent upconverter in the C8U incorporates three switchable IF inputs for redundancy, emergency alert or programming purposes, facilitating operational flexibility. These IF sources may be switched automatically or manually. The C8U is network management ready and is compatible with Motorola's NETsentry Network Management Systems via the LIFEnetTM proxy as well as with Motorola's Headend Control Software (HCS). In a digital system, the C8U can accept any digital IF signal between 41.0 and 47.0 MHz. The C8U continues the C6U legacy of handling many types of digital signals including 64 QAM, 256 QAM, 8-VSB and QPSK signals. In an analog system, the C8U supports addressable channels. An encoded composite IF signal is received from a scrambler, such as Motorola's model MVP-II, and is Upconverted to the proper RF channel for transmission.
