Audio Test and Measurement Applications

Bluetooth Audio

Test Bluetooth Audio directly!
Prism Sound's dScope Series III audio test system is the world's only electronic and acoustic test system capable of directly addressing Windows® audio devices. This enables you to route test signals directly between dScope III and your PC's Bluetooth chipset or your EUT's USB dongle. This direct connection between test system and Bluetooth device gives you immediate access to the unique dScope III feature set for your Bluetooth system tests, including sweeps, regulation, Smart FFT detectors, live measurement traces, multi-tone analysis, automation for QC applications, and much more. One of the major advantages of using dScope Series III for Bluetooth testing is that it removes the need for any time consuming generation / analysis of wave files in external software.

Test it hard!
The dScope III platform incorporates a complete suite of analysis tools for each subsystem within your Bluetooth headset, headphone or loudspeaker, including the following:

Checking the Bluetooth link for intermittent drop-outs / glitches
Evaluating ADC and DAC performance (mic input / speaker output)
Testing analogue and digital domain audio, including serial digital audio interface signals (e.g. I2S)
Characterising DSP functionality, including dynamics, EQ, noise cancellation, etc
Evaluating CODEC performance, including multi-tone testing to stress the CODEC with realistic signals
Electroacoustic measurements of microphones, earpieces and loudspeaker drive units

Test smarter, test faster!
dScope III allows you to test your Bluetooth audio devices in a closed loop from end to end, with real time control over signal generator waveforms, amplitudes and frequencies, and analysis functions and algorithms, thus greatly speeding up the process of design and test.
