dScope Series III: Computer sound devices are just another input or output...
Prism Sound's dScope Series III audio test system is the world's first electronic and acoustic test system capable of directly addressing Windows® audio devices. The dScope Series III is a combined software and hardware analysis system that treats Windows Sound devices as just another input or output (WDM or ASIO). It can generate directly to a sound card or measure using a sound card as its input - and it can do this cross-domain, analogue or digital, input or output: Want to know what your sound card does with a digital input? Send it one from dScope and let dScope look at the audio data as received by Windows. Want to know how well your sound card DAC performs? Set your sound card as the output for the dScope signal generator and measure its output using dScopes precision analogue inputs. You can analyze from the Windows software domain to and from the analogue or digital domains with no fiddling around with additional software, test files or loop-backs. It's straight forward, easy and accurate. Furthermore, you can perform sweeps and add automation just as you would with other inputs and outputs.



Take it to the board
If you want to know what your digital audio signals are doing as they traverse a PCB as serial digital data, you're going to need some specialist tools. The Prism Sound VSIO adaptor allows you to connect and map multiple channels of serial digital data such as I²S to and from the dScope Series III so you can inject and measure signals at board level. It even lets you send and receive I²C or SPI control messages, all under software control from the dScope Series III application.

Test smarter, test faster!
dScope Series III allows you to test your Windows 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.
