The Data Acquisition (DAQ) Board project is a continuation of a project that started last year. It is a project in collaboration with Western Digital. Western Digital (WD) Power LSI Systems Validation group has stress testing equipment called the Torture Stand. Inside the Torture Stand hard drives are compacted and tested until failure. However, the transient responses of voltage and current signals from the hard drives are currently obtained from oscilloscopes. The oscilloscopes are bulky and expensive, so to replace the oscilloscopes the DAQ was created. The small size and much cheaper cost of the DAQ allows Western Digital to test each drive in the torture stand. The DAQ is a prototype device that records the transient response of voltage or current signals, and stores the acquired data onto the board for later analysis. The data stored onto the DAQ is able to be transferred to a computer using PC programs and can then be displayed graphically. This document describes the design of the DAQ board, including component selection, schematic design, PCB layout, manufacturing, firmware design, and testing procedures.
