CABLE MODEM NETWORK ANALYSERS VeEX’s spectrum analyser and Calan-compatible CM3000 Series Sweep Systems and DOCSIS 3.0 cable modem network analysers are the latest additions to service and plant verification testing and troubleshooting solutions. With an intuitive user interface, VGA colour touch screen and Windows CE operating system combined with a comprehensive measurement suite and an extensive PC toolkit, the CM3000 series simplifies and speeds plant maintenance and increases quality of service. Its fast spectrum mode allows the user to view short duration ingress, impulse noise, electrical interference, CPD and other impairments on a single screen-even under upstream QAM signals. The one-button proof-of-performance CCN, CSO, CTB and HUM measurements option simplifies the testing and troubleshooting process. The WinCE Operating System helps protect the user’s investment, provides future flexibility and allows the addition of many PC-like functions, providing a one-instrument solution. Platform highlights include: simplifies proof-of-performance testing; easyto-use WinCE system minimises training and maximises testing accuracy
