DLS 400 In Stock

The Spirent DLS 400 is an advanced wireline simulator designed specifically for ADSL (Asymmetric Digital Subscriber Loop) transmission products and various other digital transmission products. This simulator accurately replicates the behavior of twisted pair copper cables, commonly referred to as wirelines, up to high frequencies. With over 30 configurable cable options, it offers extensive flexibility for testing purposes. The DLS 400 is seamlessly controlled by software compatible with Windows 95 operating system, and it supports both IEEE 488 and RS-232 interfaces, simplifying integration into larger test systems.

The DLS 400 can accommodate up to two wideband impairment generators, also known as "impairment cards," alongside loop simulations. This feature enables users to introduce a wide range of impairments to the signals transmitted through one end of the line, allowing for comprehensive testing of telecommunications transmission systems. Complying with recommended specifications from leading standards bodies. The unit's power input can be connected to an AC line voltage ranging from 100 to 200 VRMS (10% tolerance) and operating at a frequency of 50 to 60 Hz. Notably, the DLS 400 is compatible with any voltage and frequency within this range, eliminating the need for manual adjustments.

In terms of connectivity, the DLS 400 features a balanced 3-wire bantam connector, measuring 0.173" (4.39mm) in diameter. This connector, also known by various alternative names such as miniature telephone connector, mini 310 connector, and bantam telco jack, ensures reliable and standardized connections. Furthermore, the CF connector is a balanced 3-pin alternative (ring, tip, ground), and while banana plugs can be used instead, it's important to note that the pin spacing does not conform to the 0.75" spacing used in North America. The DLS 400 excels in providing bi-directional wireline simulation capabilities. Remarkably, the simulator retains the last configuration used even when powered off, thanks to the latching feature within its relays. This allows users to resume wireline simulations seamlessly without reconfiguring the unit upon restarting.

Communication with the DLS 400 is facilitated through the serial interface, with messages requiring termination by the line feed character (decimal 10, hex 0A, LF). To ensure a clean buffer before issuing new commands, users can send a line feed character independently. The simulator consistently terminates its messages with a Line Feed character for clarity and consistency. The DLS 400 incorporates essential LED indicators to provide critical status information. The power LED emits a green light when the unit is powered on, while the remote LED turns green to indicate the detection of a remote error. In case either LED illuminates in red, it signifies the presence of an issue requiring immediate attention.
