In preparation for the planned rollout of data over cable service interface specifications (DOCSIS) 3.1, Rohde & Schwarz is introducing the R&S DSA DOCSIS snapshot analysis software and the R&S FSW high-end spectrum analyser to carry out performance measurements.
The DSA software works in combination with the FSW high-end signal and spectrum analyser, which records the signals using OFDM vector signal analysis software. The analysis system is recommended for use in the research and development of cable TV network components. According to Rohde & Schwarz, it allows the signal quality of modulators for the DOCSIS 3.1 downstream to be tested when developing cable headends. For cable TV network components, the analysis software makes general performance measurements. The software is also designed to measure complete network segments under lab conditions.
These measurements can be performed using the R&S CLGD DOCSIS cable load generator, which was launched by Rohde & Schwarz in May.
