The dScope Series III Audio Analyzer enables comprehensive analysis of telephone handsets, headsets and speaker-phones. Its scripting enables loudness ratings to be calculated using a variety of excitation signals including sine, noise, multi-tones and short segments of speech. When used with ear and mouth simulators, the dScope analyzer is able to easily correct for the frequency response characteristics of these devices ensuring accurate measurement results.

For USB and Bluetooth telecommunication products, the dScope analyzer allows direct access for detailed analysis. In addition, the analyzer's real-time interactive measurements and unique Smart FFT™ capability, up to 40+ performance metrics can be measured and analyzed in real-time including distortion, noise, cross-talk, frequency response, gain, signal-to-noise, ratios of odd:even harmonics, and dynamic range among many others.
