r&s®clgd 是仿真有线电视网络全通道负载的多通道信号发生器。

the r&s®clgd is a multichannel signal generator for simulating a cable tv network with full channel loading. it generates broadband data signals for docsis 3.1 as well as digital and analog tv channels. in the downstream or upstream, signals can be freely combined, allowing users to simulate any conceivable channel loading scenario in the lab.

provides the information required to prepare the instrument for use and start working. basic operations and handling are described.

r&s®clgd 是仿真有线电视网络全通道负载的多通道信号发生器。

docsis testing requirements include supporting a full channel load and coexistence of both docsis 3.0 and docsis 3.1 signals (in some cases analog tv as well). the r&s®clgd is the only flexible and compact solution available on the market that can meet these testing requirements. the introduction of much wider bandwidths for docsis 3.1 along with higher constellation modes (up to 16kqam) require very powerful spectrum and signal analyzers. the r&s®fsw is ideal since it can measure mer that is typically 57 db and higher and also provide ber measurements based on docsis 3.1 signals.

使用 r&s®clgd 以及 r&s®fsw 对 catv 放大器进行 docsis 3.1 ber 测试

对ip 和有线电视 (catv) 更高数据率和灵活性的需求促使 docsis®3.1 问世。随着下行和上行信道宽带分别达到最高 192 mhz 和 96 mhz，且有线网络频率扩展至最高 1.2 ghz（未来将至 1.8 ghz），对相关电缆器件的技术要求已显著提高。 此应用指南描述了使用适用于 docsis 3.1 的 r&s®clgd 全频道负载信号发生器或 r&s®sfd docsis 3.1 信号发生器和 r&s®fsw 信号和频谱分析仪进行电缆器件测试的情境。

r&s®tsstream 多码流注入软件可在单个 ip 接口上同时注入多个 mpeg 码流文件。 多码流的注入会导致整体码率较高。 为使这些码流可以在电脑上使用，r&s®tsstream 软件不直接从硬盘上播放码流文件，而是首先将其加载到 ram中。 码流的最大数量和长度仅取决于电脑的可用 ram大小。
