dScope Series III

Perhaps you’re familiar with the dScope Series III and wondering how the M1 differs from it. And most importantly, which one is better for your needs. This table presents the main differences between the two analyzers.

They both include all the essential audio measurements such as THD+N, Noise, Sweeps, FFT analysis, Impulse response measurements, code-free and coded automation with support for dSNet peripherals such as the dSNet I/O Switcher (16:2) and much more.

A dScope Series III is the ideal choice If you need comprehensive AES/EBU or SPDIF interface analysis tools such as eye-pattern and jitter analysis or if you are testing power amplifiers and want the higher input voltage handling up to 159Vrms (balanced or bridged mode).  dScope Series III has a separate reference input which can be AES3 or AES11, Wordclock or Video B-B as well as “clean” digital reference outputs (Wordclock and AES) useful when performing analysis of jitter tolerance. The dScope Series III has seperate BNC connectors for digital and analog I/O and offers greater flexibility with the option of separately grounded analog generator and analyzer.  The dScope Series III also incorporates a comprehensive signal monitoring section allowing inspection on a scope of a wide variety of measurement nodes & signals within the instrument with up to 4 separate BNC monitor outputs as well as internal monitor speaker and headphone monitor outputs.
