Following the release of V1.2 software, Prism Sound has developed and enhanced the acoustics measurement capabilities of the dScope Series III platform. In addition to providing a comprehensive suite of analogue and digital electronic analysis tools, this highly sophisticated audio test unit is now able to make measurements of acoustic transducers, and supports the following functionality:

• Impulse response analysis
• Quasi-anechoic frequency response, in units of dBSPL
• Impedance (vs. frequency) analysis
• Time domain averaging to attenuate the effects of background noise
• Complete automation support including limit checking and pass / fail results, for QC / verification testing

Audio engineers can now characterize every part of their electro-acoustic systems, from A/D inputs through board-level serial interfaces to power amplifier and loudspeaker outputs, using a single audio analyzer solution in a compact package. The dScope system takes full advantage of the processing power of the host PC, enabling multiple simultaneous measurements to be made and highly flexible customizable generation and analysis tools to be supported, whilst keeping hardware costs to a minimum.

The dScope Series III analyzer platform offers some of the most flexible and powerful features of any audio analyzer on the market today. Users can define their own signal generator functions, analysis filters, analysis algorithms, FFT windows and sweep tables, in addition to being able to write custom user interfaces and to communicate with other software and hardware. dScope Series III can easily be automated using VBScript commands, enabling the creation of custom test routines with automatic results reporting. This can be accomplished using either the unit's in-built scripting environment or a third party automation executive. This makes dScope Series III ideally suited to production line testing applications, where testing of many different types of functionality in different domains can all be undertaken using this single unit.

Prism Sound's dScope Series III is a comprehensive and powerful measurement system for analogue and digital audio generation and analysis, including digital audio carrier testing, quasi-anechoic microphone/loudspeaker analysis and testing of Windows® sound devices. This industrial-strength audio test and measurement system comprises a Windows PC software application (XP® and Vista® compatible) coupled with an external high-precision audio I/O processor for equipment-under-test (EUT) connections.
