Abstract

Design and implementation of a personal computer (PC) based measurement circuits & system that containing signals’ sensing and generation are demonstrated in this study. The instrument can be easily operated via a user-friendly interface consisted of some functional keys displayed on the PC screen. Compact design of the hardware for the two units (signals’ sensing and generation) is made in a plug-in style of PC input/output (I/O) card so that no extra space for the instrument is needed. Design concepts for the hardware and software of the instrument are described. Functional performances of the setup of signals’ sensing and generation are tested. The results show user-friendly function and well-behaved performance for the package design.
