458-3SL线路仿真器

458-3SL紧凑型产品具备易使用的特点，特别适用于仅需要进行一至三个信道操作的研发工作场合。同时，对于需要在大量生产的产品线环境下进行DSL Modem和其它适应宽带的电信产品测试的情况，配备了Multi-Channel用户线仿真模块的Telebyte 458-3SL也不失为一个完美的解决方案。

通过458-3SL内置控制模块的IEEE 488接口、RS-232接口或以太网接口，在PC或其它终端上既可以利用图形化的软件也可以使用开放的用户命令语言对线路仿真模块进行环路长度及其它参数设置的控制。当然，458-3SL也可以作为独立操控的设备来使用，显示在前面板背光液晶屏上的模拟线路长度及其它参数可以通过按键编码器来进行设置。

Telebyte宽带通信公司研制的Model 4901 多路输出噪声模拟器是迄今为止世界上第一台高密度噪声模拟器，可在4U-high的主机上为用户提供2至24路独立的噪声信道，为用户提供了DSL测试的强有力的解决方案。系统可最多容纳6块AWG 板卡，每块板卡均可单独配置为2或4路信道。 通过增加AWG板卡以及配套的噪声注入器，用户可轻松地实现扩容。

Model 4901系统配备了用户界面友好的控制软件，便于用户自行选定及建立多种不同的针对DSL网络应用的损伤模型。Model 4901的共模串扰（Common crosstalk） 类型中涵盖了ADSL2+, VDSL2 以及其他诸多技术，而用户自定义串扰功能也完全符合DSL线路上的目标PSD的规范。利用MATLAB (.mat) 或者 Excel (.xls) 文件，用户能以 dBm/Hz 和相应的频率数值方式添加目标PSD。该特性能够帮助用户产生满足在DSL线路上所期望的PSD的串扰以及任意RFI tones的组合。

Model 4901多路输出噪声模拟器可以与Telebyte宽带通信公司研制的线路仿真器组成无缝连接的高精度测试环境，利用一个软件系统实现对两种设备的同时控制，无需额外增加单独的PC，为用户大幅节省了成本。
