the forefront of the test engineering industry.
SCTE 40, which establish equipment and performance requirements
It offers extensive expertise in test solutions
for high-speed data transmissions over a cable network.
spanning multiple industries and technologies
and a full range of both custom and turnkey
solutions and services.
For the broadband equipment industry,
Averna provides a full suite of DOCSIS and
EuroDOCSIS test systems to address every
phase of development—from design and
manufacturing to certification and
returns screening.
Averna’s broadband test solutions help
multiple-service operators (MSOs), equipment
makers, and industry organizations deliver
and maintain the highest quality data-overcable service despite common cable-plant
and field impairments.

The DCE Accelerates Performance Testing
The innovative DCE is a small-footprint channel-emulation platform that helps device
makers ensure that their DOCSIS and EuroDOCSIS products deliver optimum
performance in the field. At its core, the DCE simulates a real-time cable network
between the cable-modem termination system (CMTS) and customer-premises
equipment (CPE), such as set-top boxes, residential gateways, and cable modems.
The DCE’s flexible FPGA-based design is powered by the NI vector signal transceiver
(VST), which greatly expands test coverage, lowers latency, and extends bandwidth
and frequency range while minimizing the DCE hardware footprint.
Preloaded with an expandable library of industry-specified impairments like
microreflections and phase noise, the DCE helps users ensure that their
equipment meets standards such as the SCTE 40 specification.
