The world’s first complete audio test system for Bluetooth devices is set for release in January 2011 when Prism Sound’s dScope Series III audio analyser will support audio streaming directly between test system and Bluetooth device, enabling real-time, closed-loop testing of Bluetooth audio systems.

Previously, engineers have tested Bluetooth devices using a range of analogue, digital, electronic and electroacoustic audio test equipment, plus software-based signal generation and analysis tools – a time-consuming and cumbersome process that did not easily translate to automated manufacturing or verification testing environments.

The dScope Series III test system integrates analogue, digital (SPDIF and I2S), electronic, electroacoustic and Bluetooth measurement capabilities in a single instrument, eliminating the need for time-consuming signal generation and analysis in external software.

dScope Series III instrument includes precision, automatic gain-ranging which allows high-resolution analogue measurements over a range from a few micro-volts to more than 150V RMS, and from less than 1Hz to over 90kHz. Its dedicated hardware interface uses DSP to provide a wide range of real-time measurements, while its software exploits the host PC for almost unlimited number crunching and analysis options such as Fast Fourier Transforms, ‘Smart FFT’ soft instruments, swept sine and multi-tone testing. Designed to be highly programmable, the dScope Series III can be automated from a wide range of third-party software applications using Active X controls, or internally using VBScript.
