Automated Test Equipment Prototype

The analog to digital converters (ADC) used on the HCNS proved problematic, the available on-board 8-bit ADC configuration conflicted with on-chip cross-bar allocation schemes. Instead, the on-board 12-bit ADC was used to perform analog signal translation of the DHNS signal. Another UART could be employed on the HCNS for doing data dumps to a host computer. Currently data is stored using on-chip flash and dumped to a file using the Silicon Laboratories integrated development environment (IDE). Adding a UART allows real-time capture of test data for processing and reporting HCNS results. Also, if a LCD were mounted to the enclosure, feedback could be given in real-time to the observer.
