Spirent DLS-8131

The DLS 8130 VDSL2 Wireline Simulator is designed for performance testing in accordance with ITU-T North American VDSL2 Initiative ITU-T Draft Recommendation G.993.2\. This uses T1.417 cable model, and ensures complete testing coverage for multi-functional and rate-adaptive xDSL chipsets.

The DLS 8130 VDSL2 Wireline Simulator reproduces the AC and DC characteristics of twisted pair copper telephony cable using passive circuitry (R, L & C), which means that attenuation, complex impedance and velocity (propagation delay) of the wireline are accurately simulated. External noise impairments can be added to the DLS 8130. Contact Spirent for information about suitable noise impairment equipment for your testing needs.

The DLS 8130 VDSL2 Wireline Simulator consists of two chassis: the DLS 8132 and DLS 8131\. For rate-adaptive chipsets, the DLS 8130 can optionally connect to an external reach extension unit (for example, the DLS 410A or DLS 414A) for full automode or rate-adaptive testing at reaches up to 23,500 feet (23.5 kft.).

There are two methods for controlling the DLS 8130 VDSL2 Wireline Simulator: you can use the DLS 8130 Control Application which ships with the DLS 8130, or you can take control of your testing and benefit from the flexibility of the DLS 1200 ScriptCenter Library tool to write custom, script-based software to operate your DLS test system. The DLS 8130 Control Application configures and controls the system remotely through either the GPIB (IEEE 488) or RS-232 interface. Use of GPIB and RS-232 interfaces also allows for the easy integration of the DLS 8130 into a larger test system.
