MER, BER and MORE -
Everything You Always Wanted to Know About MER But Were Afraid to Ask
(pdf, 681KB)
Testing and Troubleshooting DOCSIS Cable Modem Systems
This seminar lasts about 17 minutes and covers the basics of DOCSIS cable modem systems, testing the return path for cable modem signals, testing and troubleshooting both the downstream and upstream digital signals, and special considerations for cable modems.
Why you need to test both MER and BER
This seminar lasts about 9 minutes and covers differences between modulation error ratio and bit error rate, the limitations of each and why you need to measure both to adequately test QAM signals.
Return Path Testing Seminar
This seminar lasts about 9 minutes and provides a detailed overview of the differences between testing the forward and return path, characteristics of return path signals and ingress, using a spectrum analzyer display to track down ingress, theory of the zero span display, and using the zero span display to view fast transient signals such as cable modems and transient ingress.
Constellations Demystified Online Seminar
This seminar lasts about 10 minutes and provides a detailed overview of QAM modulation and the Constellation display and how to use the Constellation display to determine the health of your system.
Modulation Error Ratio and Signal-to-Noise Ratio Demystified
This seminar lasts about 9 minutes and provides a overview of Signal-to-Noise Ratio, Error Vector Magnitude and Modulation Error Ratio. Covered is an overview of how different types of noise and interference affect digital signals, the difference between EVM and MER, how noise affects digital and analog signals differently and what is good and bad MER.
Bit Error Rate Demystified
This seminar lasts about 6 minutes and provides a detailed overview of Bit Error Rate, an overview of scientific notation, the effects of burst errors, how FEC effects BER, error seconds, and data logging.
Digital Power Measurements Demystified
This seminar lasts about 8 minutes and provides a overview of Average and Peak Power measurements on analog and digital carriers. Power bandwidth, making digital power measurements on different instruments and how to set digital carriers relative to analog carriers is covered.
Forward Error Correction Demystified
This seminar lasts about 8 minutes and provides a overview of Forward Error Correction and how it works. Also covered is an overview of the four FEC layers specified in the SCTE standard, DVS-031 used by General Instrument and Scientific Atlanta digital set tops.
T1 Transmission Theory and Testing
These three seminars cover the fundamentals of T1 transmission and framing as well as testing T1 lines. T1 forms the basis for higher level transmission formats such as T3 and SONET. These seminars form a good basis for people wishing to learn the higher levels of transmission.
DSL Theory and Testing
These four seminars provide an overview of the world of DSL. It includes discussion of the history, technology, the reality of installing DSL lines, applications, standards, types of DSL, DSL modems and the technology of
DSL.
Digital Video Measurements Application Note
Many cable systems are now implementing Digital Video Broadcast via Cable. Digital video offers the advantage of higher picture quality and more efficient use of valuable bandwidth, allowing for significantly more channels to be carried. This application note covers the various tests that cable systems should be making during the installation and maintenance of these new digital video signals in order to provide reliable high quality service to subscribers.
