РусскийATLAS NG passes the MSW certification for ATSC3 Signal Compatibility
We are proud to announce that PROMAX broadcast analyzer AtlasNG, the most advanced instrument in our range for test and measurement of ATSC 3.0 signals, has undergone a very strict and thorough test designed by Mr. Gary Sgrignoli, DTV Transmission Consultant and partner at Meintel, Sgrignoli, and Wallace (MSW, https://mswdtv.com/).
ATLAS NG is the universal broadcast analyzer supporting ATSC3 and all major DVB standards
Commercial and consumer ATSC 3.0 signal tests
MSW has curated 10 test signals for general receiver evaluation (both consumer and commercial) during ATSC3 network operation and deployment. They use a variety of modulation and transmission settings such as single/multiple PLP, TDM, LDM, and combination formats to simulate a diversity of realistic broadcast conditions, following consistently the ATSC’s A/327 recommendations.

Managing seamlessly each PLP for the ATSC 3.0 signal
Broadcasters want to feel secure that they can use a reasonable assortment of ATSC3 signal formats that will be decodable by all receivers. With this test, we have verified whether the analyzer can handle decoding all the PLP’s from each of those test signals as well as the respective SNR values it can withstand.

The results of these tests have been summarised in the chart presented down below:
