Upstream Monitoring System
Kronback X16/KWS &
Fast internet services, VoIP, online gaming…an interferencefree return path is essential for a high-quality broadband DOCSIS connection. The combination of a special KWS version of the real time X16 Kronback Tracer spectrum analyzer in the headend and the successful portable TV analyzer VAROS 107 as a field device provides a system that ensures high signal quality in the upstream frequency range.
Communication between the field device…
and headend unit is bi-directional and uses the coaxial or HFC network currently being measured. As such, no Internet connection is required. All real time spectral measurement parameters of the headend are displayed on the field device.
The 16 inputs of the headend device, its small size (19″ / 1 RU), the option to cascade up to 16 such units, and the possibility of measuring with multiple handheld devices simultaneously in the field, provide for sufficient flexibility even in large networks.
Numerous measurement and adjustment aids and an automated measurement and report generation complete this powerful system.

to the VAROS 107 field devices, an MPEG-2 data stream via Ethernet (RTP) is issued. In the headend equipment this can then be mixed in a DVB-C channel (as a separate data service).
Hybrid Fiber Coax Network: Optical and coax cable distribution network for downstream and upstream from the headend to the subscriber.
