    • Radio frequency self-certification devices and methods of using the same are provided. A device for testing a radio frequency connection may include at least one radio frequency communications interface, at least one memory, and at least one processor. The at least one memory may be configured to store computer-executable instructions. The at least one processor may be configured to access the at least one memory and execute the computer-executable instructions to (i) scan through a plurality of downstream frequencies received by the communications interface, (ii) collect, based at least in part upon the scan, information associated with a plurality of downstream channels and information associated with available upstream channels, (iii) identify one or more upstream channels that facilitate communication with a host server, and (iv) verify, via the one or more identified upstream channels, the availability of one or more client applications.

    • Systems and methods for improving performance in an HFC architecture are provided. Incoming data associated with a plurality of signals to be included in a downstream data signal may be received, and the incoming data may be mapped to a plurality of symbols representative of the signals. Data bits for each symbol may be mapped to at least one data register. The contents of the at least one register may be read by one or more digital-to-analog converters to facilitate a direct radio frequency synthesis, and the output of the one or more digital-to-analog converters may be provided to one or more electro-optic conversion devices configured to output a downstream data signal.
    • 提供了一种用于提高HFC架构性能的系统和方法。 可以接收与要包括在下游数据信号中的多个信号相关联的传入数据,并且可以将输入数据映射到表示信号的多个符号。 每个符号的数据位可以映射到至少一个数据寄存器。 至少一个寄存器的内容可以被一个或多个数模转换器读取以促进直接射频合成,并且可以将一个或多个数模转换器的输出提供给一个或多个 被配置为输出下游数据信号的电光转换装置。
