Spirent DLS 5900
G.FAST Noise Impairment Generator xDSL Wireline
and Noise Testing Solutions
The requirement for high-speed
transmission over the traditional
copper network has driven the
continuous advances in DSL
technology.
Overview
Network equipment manufacturers, chipset designers
and service providers seek competitive advantage
by being first to deliver reliable products or services
to market. Spirent supports these efforts by providing
Impulse shaping
functionality
testing solutions that enable first results for exacting conformance and performance standards.
DLS 5900 allows users the ability
The Spirent DLS 5900 is a flexible noise impairment generator developed for G.FAST
to shape both time and frequency
domain parameters
Users selectable filter for start and
stop frequencies
Spirent solution users know that this advantage translates into robust performance, earlier product
delivery and greater market share. DLS 5900 helps address this market requirement.
requirements. The impairment generator is packaged with a user interface tool to allow easy
creation and customization of a variety of noise conditions. Spirent DLS 5900 will allow a user to
create a continuous and background noise, power line transmission (PLT), impulse and RFI noise.
These noise conditions/types are problematic for G.FAST transmissions. Spirent DLS 5900 series

G.FAST systems therefore requires a testing solution for this new frequency range, capable
of generating various types of noise impairments that are to be expected in the operational
environment. The DLS-5900 is just that: a powerful, versatile, flexible tool for the generation of
impulse, RFI, PLT and other continous noise, capable to produce all the noise that you will need to
test G.FAST.
