The VeSion Return system monitors the return path for noise, UCD and ingress that interfere with DOCSIS communications. With DOCSIS 3.0/3.1 deployments, higher order upstream QAM modulation and channel bonding are more vulnerable to ingress and should be monitored continuously to ensure peak performance.
As part of the VeSion system, the CX180R sets new standards for form factor and performance. The space saving 1U rack mount unit integrates multiple DSP based test resources dedicated to 10 nodes in each system. Each CX180R unit supports three different test modes simultaneously and independently. In ingress scan mode, fast transients can be identified at a scan rate of up to 250ms per node. In spectrum analyzer mode, on demand RF signal analysis using optimal programmable RBW and dwell time can be performed.
