product overview

Now you can capture live field noise and export it to a wide variety of formats. The DSL Field Noise Capture Solution is a portable high-performance system that records, displays, saves and analyzes samples of live noise for realistic Interoperability testing, circuit qualification, debugging of error conditions, lab design and more.

Bring live noise from the field back to the lab for injection into test loops. Prepare crosstalk and impulse files for export to the Model 4901 Multi-Output Noise Generator with this 30-MHz system, capable of transparently capturing ADSL2, ADSL2+ and VDSL2 noise. The MATLAB-based interface provides convenient options for range selection, sampling rate, capture length and more. The solution operates in three capture modes for control of recording of time.

The Solution also acts as a real-time, general purpose, portable data acquisition system. This convenient feature can be used during installation and maintenance or for spectrum monitoring and analysis to support documentation and reports on the field environment.
