DLS 400J In Stock

The DLS 400J by Spirent is an advanced Japanese ADSL Wireline Simulator that serves as a crucial tool for testing the functionality and performance of various wireline technology-based devices, including ADSL devices. The primary function of this simulator is to accurately replicate the characteristics of twisted pair telephony cables, encompassing diverse types, lengths, and configurations. By emulating these cable properties, the DLS 400J enables comprehensive testing of devices based on different coding techniques such as CAP, DMT, and 2B1Q.

To enhance its testing capabilities, the DLS 400J works in conjunction with the DLS 5102 simulator, which introduces impairments such as impulse, shaped, and white noise. Together, these two simulators offer a comprehensive testing solution for evaluating the performance and robustness of wireline technology devices. Flexibility is a notable feature of the DLS 400J, thanks to its unit modularity. Users have the freedom to combine units according to their specific testing requirements. The attached Unit/Test Loop Matrix provides a clear overview of the coverage offered by different combinations, ensuring adaptability and customization in testing setups.

Operating with the supplied DLS 1100 Series software, which is compatible with Windows™, the DLS 400J facilitates seamless integration with a user's PC. The PC and simulator connection can be established using either an IEEE 488 interface or a regular RS-232C serial cable, offering versatility in connectivity options. The user-friendly software empowers users to effortlessly select desired test loops and noise settings, streamlining the testing process. Complying with the ITU Standard for G.992.2 (G.Lite), the DLS 400J encompasses all necessary test loops and impairments specified in the standard. By incorporating "sections" of passive components that are selectable by the user, the simulator can precisely replicate desired cable lengths. This ensures that this simulator delivers consistent and comparable reference standards, thereby facilitating accurate and reliable testing procedures.
