Executive Summary

The advent of a wide range of USB peripherals for personal computers has altered the test and measurement landscape. In particular, easily portable and inexpensive USB logic analyzers, such as the DigiView DV1-100, have enabled a host of industry-specific test applications. Such a logic analyzer used in conjunction with the Dynamic Engineering SpaceWire BreakOut (DESWBO, http://www.dyneng.com/deswbo.html) and an inexpensive notebook computer allows users to implement a portable and capable SpaceWire troubleshooting tool. Support software included with USB logic analyzers typically provides a myriad of display options, large data capture buffers, specialized trigger functions, and a variety of data export alternatives, including waveform images and ASCII files.
