Prism Sound's dScope Series III audio analyzer has been upgraded so support audio streaming directly between test system and Bluetooth device, enabling real-time, closed-loop testing of Bluetooth audio systems.
Up until now, audio engineers have usually tested Bluetooth devices using a range of analog, digital, electronic and electroacoustic audio test equipment, plus software-based signal generation and analysis tools. This was not easy to use in automated manufacturing or verification testing environments.
The dScope Series III test system integrates analog, digital (S/PDIF 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.
Prism Sound's (Cambridge, UK) dScope Series III instrument includes precision, automatic gain-ranging which allows high resolution analog measurements over a range, from a few micro-volts to more than 150 volts RMS, and from less than 1 Hz to over 90kHz.
Its dedicated hardware interface uses DSP to provide a range of real time measurements, while its software exploits the host PC for almost computation and analysis options such as Fast Fourier Transforms, unique 'Smart FFT' soft instruments, swept sine and multi-tone testing.
The programmable dScope Series III can be automated from a range of third-party software applications using Active X controls, or internally using VBScript.
Prism Sound will be demonstrating live measurements on Bluetooth audio devices at the CES in Las Vegas in January.
