AMA 310/UMS & VAROS 107
Upstream Measurement System
This system combines the KWS devices AMA 310/UMS and VAROS 107 to a high-end monitoring system for the return path frequency range. An AMA 310 in a 19-inch version (3.5 RU) with UMS module is used in the headend, in the field the CATV hand- held VAROS 107 is the counterpart. Both devices communicate bi-directionally through the cable or HFC network to be measured. Thus no internet connection is necessary.
An optionally available 24-fold RF switch (model type SW 024) and the handover of the measuring results to the headend equipment either in ASI format or as an IP data stream (UDP or RTP/UDP) lead to great flexibility when measuring as well as when connecting the entire monitoring system to the headend equipment.
AMA 310/UMS&VAROS 107
Cluster selective measurement with 24-fold switch SW 024
The RF switch SW 024 (19-inch, 1 RU), which is available as a separate option to the AMA 310/UMS in the headend, allows for measuring up to 24 clusters or CMTS upstream inputs separately.
Kronback X16/KWS& VAROS 107
Upstream Monitoring System
Fast internet services, VoIP, online gaming … an interference- free return path is essential for a high-quality broadband DOC- SIS connection.
The combination of a special KWS version of the real-time spectrum analyzer X16 by the Danish company “Kronback Tracers” in the headend and the successful cable handheld 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 in 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 units, and the possibility of measuring with multiple handheld devices simultaneously in the field, provide for sufficient flexi- bility even in large networks.
