BY-302B digital / analog audio analyzer

    BY-302 innovative design includes: one-press test, automatic sequential execution and continuous scanning technology, it only takes 7 seconds to measure 14 parameters. All measurement panels are very intuitive and can examine the results from multiple perspectives and check the upper / lower limits of the graph. Automatic sequencing or API programming automatically repeats testing of parameters for different signal levels and real-time monitoring of level, waveform and spectrum analysis. With external source mode, clients' waveform files can be played to measure CDs, DVDs and MP3 players.

    BY-302B High performance, typical THD + N up to 110 dB and 24-bit resolution FFT spectrum analysis up to 1MHz with AG52 and BW52 options; BY-302B displays power and frequency graph relationships and other CEA-2006 / CEA-490A measurement. It is also the only CMRR common mode rejection test in the world to provide the IEC60268 section 14.15.1 standard.
