For cable TV, the "last mile" to the connection at the home is the bottleneck that prevents higher data rates. The last mile is made up of optical fiber and coaxial cables, amplifiers and electrical/optical converters. This mix of optical fiber and coaxial cables is known as a hybrid fiber coax (HFC) network. One option for cable network providers to maximize both the downstream (DS) and upstream (US) data throughput using the existing cable TV network, but without making expensive changes to the HFC network infrastructure, is to employ the data over cable service interface specification (DOCSIS) 3.1. This Application Note discusses the fundamental technological advances of DOCSIS 3.1 and presents measurement solutions from Rohde & Schwarz.

Reverberation Chambers (RVC) have become popular as an alternative to Anechoic Chamber (AC) facilities for electromagnetic emission & immunity tests. Unlike AC, RVC reflects waves creating multipath environment. EMC testing using reverberation chamber is accepted in various EMC test standards across different industries. The RVC is cost effective allowing high field strength generation without excessive amplification needs, eliminates the need for complex positioning of antennas and DUTs increasing test speed and simulates real-world electromagnetic environments more accurately. To ensure accurate and efficient testing, specialized EMC test software is required for data acquisition, automation, and analysis. This application note describes how to setup Elektra and perform measurements in RVC.
