4801-NT Custom Noise Tool

The Custom Noise Tool is a software application specifically designed to work with Telebyte’s Model 4801 Universal xDSL Noise/Interference Simulator. This user-friendly application generates impairment models common to DSL network implementations and greatly expands the noises available beyond the current 4801 libraries. The Custom Noise Tool allows for expedient development of impairment noise files that can be exported to our Model 4801 for injection into a local loop simulator. The user can simulate a wide variety of crosstalk scenarios and noise characteristic combinations for testing any flavor of DSL as well as user-specific configurations.

This highly-advanced system allows manufacturers of today’s xDSL technologies to test signaling 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).

Our LabVIEW-based control software includes features such as straightforward selection of test parameters, control of Telebyte wire line simulators, archiving of test setups and graphical representations of selected noise types. Remote control via RS-232, Ethernet or GPIB for scripting is also available.

The Model 4801 also includes an Analog Waveform Editor. This powerful and easy-to-use tool is used to build and export waveforms to standard formats. Features include: support for NI-HWS, LVM, ASCII and binary files; a library of approximately 20 built-in primitives, support for very large waveforms and the ability to save data with specifications so it can be easily manipulated at a later time.
