The Spectral Measurement dScope Series III audio analyzer (formerly Prism Sound dScope Series III) is an industrial strength audio test and measurement system comprising a Windows PC software application coupled with an external high-precision audio interface processor for equipment-under-test (EUT) connections.

The dScope Series III architecture makes the most of the ever-increasing processing and multi-tasking capabilities of the Windows platform to allow the system to measure many parameters simultaneously - and that means faster. The external interface processor connects to the PC via a standard USB connection making it easy to use with a wide range of PCs, including laptops.

The external interface processor includes precision analogue and digital outputs and inputs that are highly optimized for measurement applications. Precise and automatic gain ranging allows high resolution measurements over a phenomenal range from a few micro-volts to more than 150 volts RMS, and from less than 1 Hz to over 90kHz.

The dScope Series III interface processor uses dedicated DSP to provide a wide range of real time measurements, and the software uses the host PC for almost unlimited number crunching and analysis options such as Fast Fourier Transforms (FFT),  power spectrum analysis, swept sine and multi-tone testing.

The dScope interface processor also provides controlled degradation and analysis of AES3 and S/PDIF digital audio carriers. The software also allows the dScope to use installed Windows sound devices such as sound cards or Bluetooth audio headsets as generator outputs or analyzer sources.

dScope Series III is highly programmable - great for production test automation and for specialized custom audio analysis. It can also be automated from a wide range of third party software using ActiveX controls - almost anything you can do with dScope can be automated and controlled remotely.

In addition, the rich feature set of dScope Series III means that it can do the job of many traditional instruments which in turn means cost savings, especially when it is time for re-calibration !
