X16 HFC Analyzer

The Kronback Tracers X16 is a DOCSIS 3.1 compatible suite of HFC monitoring tools such as returnpath analyzer, sweep system, downstream carrier monitor. Returnpath monitoring includes an advanced quality engine to log history information of noise and quality and alerts if ingress is present. Features such as NMS gateway and a dedicated RF switch increases the flexibility.

A full featured interactive tree-structure of the HFC plant, integrated with major GIS providers, ensures that users can locate noise source in an effective and proactive way. The analyzing of amplifiers actions by the X16´s advanced quality engine presented to the user immediately.

Returnpath spectrum analyzer
The Kronback Tracers X16 returnpath analyzer provides real-time and history spectrum analysis. The returnpath range is 3-204 MHz. Groups of X16 units can monitor an unlimited number of returnpaths within each headend. The X16 is accessed via all major web browsers and can also be controlled from smartphones and tablets. Multiple concurrent users can access individual returnpath signals simultaneously while history logging of all returnpaths is performed.

Returnpath quality
The quality of all returnpath inputs is evaluated online and ranged from 1 to 5. This ensures that users have a fast and tangible overview of the overall network performance.

Sweep systemThe X16 features is a powerful up- and downstream sweep system supporting the full returnpath range of 3-204 MHz and downstream from 50 up to 1218 MHz. Together with the compact and flexible P4i field unit a full and precise network alignment can be performed effectively.

Carrier detection
Carrier monitoring of all downstream carriers can be performed in the range from 50 to 1218 MHz. Individual channel plans can be programmed for each input.
Precise readout of analog and digital carriers are presented online and as history information. Alarms can be dispatched based on programmable thresholds.

Full range RF switch
The 16 inputs of each X16 can be switched to a dedicated output. The switch features a high linearity high isolation single-pole-16-throw switch. The switch and combiner can be used as preselection switching for 3rd party measurement equipment in the headend.

NMS Gateway
Using the dedicated NMS slot, the X16 features is a full FSK communication system for control and monitoring of FSK devices in the HFC network. Support of HMS and proprietary protocols is provided and can be combined with a powerful HFC topology view.
