Real-time OFDMA & ATDMA Signal Analysis
Real-time DOCSIS OFDMA and ATDMA burst receivers are available in a statically configured mode, a dynamic in plant SFD test mode, and dynamic analysis of live cable modems - communicating in the network without operational network impact. As a real-time receiver, it provides accurate long term BER measurements.
Real-time SC-QAM and OFDM Signal Analysis
Real-time DOCSIS SC-QAM (J.83 Annex A/B/C) and OFDM receivers offer multiple signal measurements, most significantly a method of measuring long term BER statistics.
Dynamic Upstream Analysis
Using both its upstream and downstream analysis, the DSA can lock onto a CMTS OFDM or SC-QAM downstream communication channel and interpret timing.
DSA also upstreams transmission information without any impact to the network to provide RF ATDMA and OFDMA upstream performance measurements at any point in the network.
Cable Modem Ranging
The DSA with its sister product the SFD can range both DOCSIS 3.1 and legacy cable modem for production verification of equipment before it ships.
Synchronous OFDM Spectrum Analysis
An OFDM carrier spectrum analyzer with the sample clock tied to the modulated carrier’s symbol clock, allows for accurate adjacent channel measurements.
