The MTS400 Series MPEG Test Systems provide a comprehensive and integrated suite of real-time and deferred (offline) analysis tools. The tools include TS (transport stream) compliance, buffer, PES, MPEG2, and MPEG4 video and audio elementary stream analyzers. Also included are an editor and a multiplexer to create stream content, and test and error-stressing streams. Standards compliance is ensured though built-in customizable scripting, which supports a broad range of ratified and evolving DTV standards. New standards and proprietary tables can easily be implemented by loading Tektronix supplied updates, or creating your own custom scripts. The MTS400 series instruments have a large LCD display with a powerful 2.8 GHz processor with support for multiple physical layer interfaces such as ASI, SPI, SMPTE310M, RF, including QAM (annex B), COFDM DVB-T, QPSK/8PSK, and 8VSB, and IP (10/100 BaseT and Gigabit Ethernet).
