DLS-8131 In Stock

The DLS-8131 by Spirent is an advanced VDSL2 wireline simulator chassis, specifically designed as a comprehensive solution for conducting tests on multi-functional and rate-adaptive xDSL chipsets. With its utilization of the T1.417 cable model, the DLS-8131 simulator ensures accurate and complete testing coverage. It meticulously reproduces the AC and DC characteristics of twisted pair copper telephony cable by means of passive circuitry (R, L & C). This enables the simulation of critical parameters such as attenuation, complex impedance, and velocity (propagation delay) of the wireline. Furthermore, the simulator allows for the introduction of external noise impairments, delivering a comprehensive testing environment.

The DLS-8131 simulator can be controlled with a compatible control application. Alternatively, users have the flexibility to assume manual control over the testing process, harnessing the power of the ScriptCenter Library tool to create custom, script-based software tailored to their specific needs. The control application facilitates remote configuration and management of the system through both the GPIB (IEEE 488) and RS-232 interfaces, making integration with larger test systems a seamless experience. This exposed metal of the DLS-8131 must be grounded via a protective grounding conductor in the power cord to ensure proper operation and protection. The corresponding symbol indicating a protective grounding conductor terminal can be found in the equipment's documentation.

On the front panel of the DLS-8131 there is a variety of essential features. It includes an RJ-45 connector for wireline Side A, another RJ-45 connector for connecting an extension unit, a power LED indicating the power status, a remote LED indicating the remote status, an additional RJ-45 connector for connecting an extension unit, and a final RJ-45 connector for wireline Side B. The power LED illuminates green when the unit is powered on, turns red if the chassis fails the self-test, and appears yellow when an internal error is detected. Similarly, the remote LED remains off after a power-up or reset, but turns green upon receiving valid commands and red if a command generates an error. The red LED persists until the error flags are cleared, typically caused by an invalid command or an out-of-range value.

On the reverse side of the DLS-8131 unit, several vital components contribute to its exceptional performance. These include an IEEE 488 (GPIB) address DIP switch, allowing for easy configuration of the GPIB address, a power switch for convenient operation, a power input to connect to an AC power source, an RS-232 connector to establish a connection with a computer for remote control, a fuse box housing two type "T" 2A/250V slow blow fuses, an IEEE 488 (GPIB) connector for remote control connectivity, and a reliable power supply. Proper ventilation is crucial for optimal functioning and safety, so it is essential to ensure that the ventilation holes remain unobstructed. Additionally, it is recommended to operate the equipment with a minimum clearance of 10 mm from the ventilation holes to ensure adequate cooling.
