(click thumbnail)Prism Sound says it has been enhancing the acoustics measurement capabilities of its dScope Series III platform. The audio test unit is now able to make measurements of acoustic transducers, and supports impulse response analysis; quasi-anechoic frequency response, in units of dB SPL; loudspeaker rub and buzz detection; and loudspeaker loose particle detection.
Additional highlights include impedance (vs. frequency) analysis; time domain averaging to attenuate the effects of background noise; and automation support including limit checking and pass/fail results for QC/verification testing.
Audio engineers can characterize each part of their electro-acoustic systems from A/D inputs through board-level serial interfaces to power amplifier and loudspeaker outputs. The dScope system takes advantage of the processing power of the host PC, enabling multiple simultaneous measurements and support for customizable generation and analysis tools.
dScope Series III users can define their own analysis filters or calculation algorithms. The system can be automated using VBScript commands, enabling the creation of custom test routines and pass/fail limit checking. This can be accomplished using the unit’s scripting environment, or alternatively dScope Series III can be controlled from within a third-party automation executive.
