Test, Measurement and Monitoring in Cable’s New World

Test, Measurement and Monitoring in Cable’s New World

It is obvious that the cable industry is changing with unprecedented speed. New services and new ways of delivering those services are emerging on a consistent basis. One thing remains the same, however: Operators must deliver what they promise reliably and without drama. To promise and fail has dire consequences.

TV Everywhere, Part II: Farther Down the Road to Revenue

special-report-enl

TV Everywhere is happening today – though the technology, systems and procedures still are in flux. The challenge for cable operators is to jump into this promising sector, but in a way that strands as little investment as possible and creates infrastructure that simultaneously can support other services. It’s not easy – but it’s not an option.

White Paper: Recreating the Field in the Lab – CATV Network Simulation

rs-featured

Whether you’re a developer looking to test your latest design or a network engineer evaluating equipment prior to deployment, realistic simulations of a cable network are a key part of exposing components to operating conditions in the field. This approach is particularly useful when developing or assessing cable TV receivers and amplifiers, which must cope with many different types of interference effects.

White Paper: Understanding Frequency-Specific Cable Egress

white-paper-r-s

Whether you’re responsible for maintaining a CATV network or an LTE network, egress from cable television systems has become one of the more serious sources of interference in 700 MHz LTE networks in the United States. Traditional tools and methodologies for detecting and locating egress are focused almost entirely on analog signals in the VHF aeronautical band and therefore cannot be used for digital signals at higher frequencies.

Special Report: What is Signal Level? – Part 2

ebook-enl

When you measure signal level at the output of an amplifier, the input to a cable modem, TV set or set-top, just what is it that’s being measured? The short answer is you’re measuring the amplitude of a signal or signals, but what does that mean? And is measuring signal level enough? Understanding the nuts and bolts of signal level is an important skill for all technical personnel.

Special Report: What is Signal Level?

ebook-featured

Join industry veteran Ron Hranac – past SCTE President, Chairman and Hall of Fame inductee, and Technical Leader for Cisco Systems – as he explains the basics of just what signal level is in the first of a two-part eBook, What is Signal Level? Ron discusses the importance of equipment calibration, provides troubleshooting tips, and emphasizes the importance of understanding the limitations of signal level measurements: Sometimes signal level is OK, but signal quality is not.

White Paper: Evolving Challenges in LTE / Cable Interference Issues

rs-featured

The widespread deployment of LTE at 700 MHz has important implications for the cable industry with regards to signal ingress and egress. Awareness of this issue in both the cable and wireless community has grown tremendously since it was initially identified, and tools for detecting, locating, and resolving cable egress issues are now available.
