Product Detail

MKQ128 is a powerful and use-friendly QAM Analyzer intended to monitor and report the health of the Digital Cable and HFC network. 

It’s able to continuously log all measurements values in report files and to send SNMP traps in real-time if selected parameters’ values over defined thresholds. For troubleshooting a WEB GUI allows remote / local access to all monitored parameters at the physical RF layer and DVB-C / DOCSIS layers.

As the number of Digital Cable TV and DOCSIS subscribers keeps increasing worldwide and Quality of Service has become a significant element to reduce subscribers churn, MKQ128 is the ideal tool to achieve cost-effective 24/7 monitoring of the quality delivered to all points of a Digital Cable network. The cable operator can deploy it at the headend / hub, along the last mile, or at the subscriber premise. 

MKQ128 is a sub-system as rackmount to continuously monitor frequency/amplitude/constellation/BER responses for all QAM channels. By using these monitoring parameters, operator can be proactive in correcting the cable quality issue and also to locate the area where degradation is impacting service.
