Sweep System & Cable Modem Network Analyzer

The CM2800 sets a new standard for CATV plant maintenance. For the first time, a high-resolution, non-intrusive sweep function has been combined with triple play service and network analysis to validate the network’s capacity to deliver next-generation services. This comprehensive tool is the only instrument necessary to help reduce outages and optimize the crowded upstream for DOCSIS 3.0.

With a truly modern sweep system that provides exceptional graphics display, the CM2800 enables operators to detect the smallest of impairments before they affect customer experience. Its intuitive user interface, automated measurements and familiar Windows CE operating system simplify and speed plant maintenance.

Highlights

• Easy-to-use WinCE system minimizes training and maximizes testing, accuracy and consistency
• Compatible with existing CaLan sweep systems already in the field
• Interfaces to Sunrise Telecom’s web-based realGATE management system, providing a full array of tools for tracking assets, analyzing test data and implementing workforce management
• High-resolution, true non-interfering 5 to 1100 MHz downstream sweep system
• Fast high-resolution 5 to 200 MHz upstream sweep with ingress detection

Applications

Sweep System

CM2800 qualifies the network for today’s expanding subscriber services, checking both downstream and upstream paths and ensuring proper frequency response and level. This may be done from any point in the network with CM2800’s ability to save test results and use the results as a reference trace.

Upstream Sweep

The CM2800 upstream transmitter covers the frequency range from 5 to 200 MHz and transmitter output levels of 10 to 50 dBmV. Although diplexers limit the frequency response of the amplifiers, upstream lasers can be tested to their full 200 MHz capability.

When a referenced sweep is performed, the difference between the reference and the current sweep is displayed, thus allowing the user to view the difference in the frequency response and level from the reference point to the current test location.

Downstream Sweep

Un-paralleled sweep speed, accuracy and resolution combined with non-interference make the CM2800 and 3010 the ideal downstream sweep solution. With 5 to 1100 MHz frequency range the user can view the utilized bandwidth and band edges of any network. Display controls allow the user to set start & stop or center frequency and span or scroll through any portion of the spectrum.

Simultaneous display of the low & high pilot with pass/fail limits and the sweep trace make network setup and balancing simple and fast. Markers allow the user to view the level at any frequency and to make Tilt and Peak-to-Valley measurements between the marker settings.

The CM2800 supports DOCSIS and Annex B & C. The CM2800E supports DOCSIS/EuroDOCSIS and Annex A, B & C.
