Long Loop ALC

By Ron Hranac — A surprising amount of behind-the-scenes interaction occurs between Data-Over-Cable Interface Service Specifications (DOCSIS®) cable modems and the cable modem termination system (CMTS). One important process is called station maintenance.

Total Power and Power Spectral Density

By Ron Hranac — Two RF power-related parameters that can cause confusion are total power (also called total composite power) and power spectral density (PSD). Grab a cup of coffee and a scientific calculator.

How Adaptive Equalization Works

By Ron Hranac — Let’s first look at the concept of equalization from the perspective of a cable distribution network. As you know, in a given length of coaxial cable higher frequencies are attenuated more than lower frequencies.

An Introduction to PNM

By Ron Hranac — Linear distortions—micro-reflections, amplitude ripple/tilt, and group delay distortion—wreak havoc upon the digital signals carried in our cable networks.

Signal Leakage Field Strength

By Ron Hranac — Cable operators for decades have dealt with the monitoring and measurement of signal leakage field strength. But just what is field strength?

Cable-Tec Expo Recap 2018

By Ron Hranac – First and foremost, a tip o’ the hat and a big thanks to Expo Program Chair Kevin Hart, Executive Vice President and Chief Product and Technology Officer for Cox Communications; members of the Program Committee; the Society’s Board of Directors.

Two-way Splitters: A Peek Under the Hood

By Ron Hranac — In this second installment of a three-part article, the discussion about measurement of downstream RF signal levels continues.

Did You Know?

By Ron Hranac — Earlier this year SCTE·ISBE’s Rocky Mountain Chapter instituted a new program called Last Thursday, a monthly meet-up on the last Thursday of every month. The meetings are open to all chapter members, guests, and those interested in SCTE·ISBE, and provide a fun and social way to participate with the chapter.

Measuring Cable TV Network Downstream RF Signal Levels (PART THREE)

By Ron Hranac — Making accurate signal level measurements is not quite as simple as it might seem at first glance. This installment concludes the discussion about various factors that can affect those measurements, and includes tips to ensure more accurate and reliable results.

Cable-Tec Expo Recap 2017

By Ron Hranac – During the week of October 16th, some 8800 people made their way to the Colorado Convention Center to attend 2017’s SCTE·ISBE Cable-Tec Expo. The last time Expo was held in Denver was September 2014, and Mother Nature surprised attendees with snow — lots of it.
