The ByteBlower :: Blowing Bits and Bytes - Cool Tech The team at Excentis, located in Ghent, Belgium, have really outdone themselves with an incredibly cool packet generator which was on display at the Anga Cable 2012 show. This is their second generation on the product, called the ByteBlower 2100. It builds on the previous model, the ByteBlower 1000. What does it do? It generates packets of data - lot's of them and very quickly and accurately. Why is this important? For everyone who has a test lab and needs

Why is QAM Getting Me Down?

Mia Colabrese2021-08-18T09:11:04-04:00May 2nd, 2012|

64-QAM lower than Analog video on the downstream? 64-QAM lower than 16-QAM on the upstream? Why is a 6.4 MHz channel lower than a 3.2 MHz DOCSIS channel? Someone said there is math for all of this, but man QAM is getting me down! These questions come up in every lecture I give on DOCSIS. Why do QAM measurements show up at different levels on a spectrum analyzer than analog measurements. What's more, why do QAM signals of different bandwidth have different levels? Some of the questions have

Impact of Impulse Noise on Adaptive Pre-Equalization Part II

Mia Colabrese2021-08-18T09:36:31-04:00March 1st, 2012|

In part I of this article I discussed adaptive pre-equalization in DOCSIS cable modems and how it can compensate for many upstream impairments such as frequency response, group delay and micro-reflections. I also left off with a cliff-hanger, which is also the title of the article; impulse noise has an impact on adaptive pre-equalization, but how and what is it? I'll cover both what impulse noise is and why and how it impacts adaptive pre-equalization.

Impact of Impulse Noise on Adaptive Pre-Equalization

Mia Colabrese2021-11-24T09:26:04-05:00February 29th, 2012|

For those of you who have attended my seminars you are familiar with adaptive pre-equalization in cable modems (if not I'll explain it in detail momentarily). Also, if you have done any amount of RF plant troubleshooting you are certainly familiar with Impulse noise (again, I'll cover this too). But if you are like me, I never knew that the two topics were co-related.
