THD Podcast 30 - Single Board Audio Measurement Instrument - Swiss Army Knife for Audio Engineers

The Total Harmonic Discussion / the THD Podcast. A weekly discussion on audio and headphone technologies and the people who bring the technology to market. In episode 30, our usual co-host Simon Weston has the table flipped to present his audio test and measurement computer - the ZUMI CS-A86. The ZUMI CS-A86 is a single board audio spectrum measurement instrument. The CS-A86 operates autonomously to execute advanced measurement sequences, apply for pass-fail criteria, and log all data.

The device is aimed at implementation in automated test equipment for production and development. The primary function is to obtain frequency response function measurements for DUT's that require testing of signal paths, especially involving filter structures or other signal conditioning elements. The built-in capability to configure DUT's via serial interfaces allows a comprehensive set of quality control tests to be completed without user input.

The CS-A86 provides 6 analog input channels and 2 hard wired output sense channels. All channels are sampled simultaneously at up to 100kHz with 18bit resolution. The CS-A86 package includes an LCD display based UI board for displaying measurement result.
