Sunrise Telecom bows new cable TV spectrum analyzer for ops

Equipment vendor Sunrise Telecom has introduced a new cable TV spectrum analyzer that was designed to improve modulation error rate (MER) performance in cable operators' networks.

Sunrise said the new analyzer, AT2500RQ4, could help ensure that operators eliminate problems in the network before they affect the end customer experience.

AT2500RQ4 features include automated digital proof of performance test capabilities, answering cable operators' need for a tool that assesses the quality of a rapidly expanding range of digital video services.

Cable operators are in the midst of replacing analog signals with bandwidth-saving QAM signals as they expand their all-digital video programming slate, delivering linear digital channels, as well as video-on-demand, HDTV and digital video advancements such as 3-D TV. Consequently, broadband network technicians face the challenge of keeping the all-digital cable plant operating at peak performance at all times.

Sunrise said the AT2500RQ4 allows technicians to quickly perform sophisticated tests and get accurate results at higher MER levels. In addition, the unit's automated digital proof of performance test allows users to test the entire digital channel spectrum with the push of a single button.

"The demand for digital video continues to grow at a very rapid rate, and cable service providers are reacting to bandwidth demand, aggressively deploying 'all-digital cable plants,'" said Bahaa Moukadam, CEO of Sunrise Telecom. "However, along with improved bandwidth efficiency, digital networks can be far more susceptible to performance degradation from network impairments. Using the Annex A-compliant AT2500RQ4, technicians have access to an easy-to-use solution that ensures cable subscribers are receiving digital video selections without any disruption."
