Telebyte presents the innovative Model 4801 Universal xDSL Noise/Interference Simulator, featuring the lowest noise floor of any noise simulator on the market today.

 

The 4801 Series is a highly-advanced system allows manufacturers of today’s xDSL technologies to test signalling devices such as transceivers and DSLAMs with ease and accuracy. Our design uses unique technology to achieve real-life noise simulation, allowing for accurate and repeatable testing.

 

Reduce clutter with this all-in-one unit that includes a powerful built-in PC, eliminating the need to add a PC to the test configuration. The Universal xDSL Noise/Interference Simulator seamlessly integrates with our outstanding line of wire line simulators for the ultimate in affordability, accuracy and ease of use. Modular design allows for a system that can be expanded as needed. The expandable Noise Library system will include new noises as standards are established (e.g., ETSI, ANSI, ITU and the DSL Forum).
