Sunrise Telecom has a firmware upgrade for its cable modem test products the company said provides a significant increase in technicians’ ability to analyze and troubleshoot the RF and fiber distribution network.

The upgrade is for the company’s CM3000 Cable Modem Network and Spectrum Analyzer and CM3800 Sweep System and DOCSIS 3.0 Cable Modem Network Analyzer, new or already deployed.

Version 2.23 of Sunrise’s firmware has new features that include a 0.3 μSec sample rate and 100 mSec sweep rate to capture even the shortest bust of ingress, impulse noise or electrical interference in the upstream path.

In addition, equalizer stress, frequency response and group delay measurements have been added to the cable modem and digital video analyzer functions, the company said.

“The firmware release is significant to the cable TV industry because it vastly improves the capabilities of our CM3000 product family to give technicians the ability to identify and resolve network impairments before they actually impact the customers,” explained Jack Webb, product manager at Sunrise Telecom. “These performance enhancements enable technicians to accurately troubleshoot difficult electrical interference and short duration impulse noise problems – capabilities that are beyond the scope of typical Digital Service Activation Meters.”
