Since its advent in the early 1970s the logic analyser has become arguably the most important single piece of test equipment in the digital designer’s armoury. It is now a far more versatile instrument than its early predecessors， still offering a complete solution to today’s ever more complex digital design and measurement challenges. As with most modern test equipment， the ongoing development of logic analysers has been fuelled by continual improvements in microprocessor technology， allowing cost-effective implementation of advanced measurement techniques. This continual development has been driven， to a great extent， by the need to be able to debug complex microprocessor-based or highspeed state machine designs. As the inclusion of microprocessor or VLSl components into circuit design becomes more and more routine， the instrument manufacturer must maintain the logic analyser as a user-friendly， relatively-low-cost solution to modern digital design and test problems. In addition， however， as these components increase in both complexity and performance， the instrument manufacturer must be able to support state-of-the-art measurement techniques， while still offering the digital design engineer the same depth of general-purpose circuit analysis.Clearly， as design complexity increases， an increasing volume of measurement data must be represented and manipulated in such a way that it can be quickly and easily interpreted by the engineer. The basic logic analyser provides a means of monitoring software execution， digital hardware operation and， more importantly to many， the interaction between the two. Being the only instrument that can comprehensively bridge this notional divide between hardware and software， the logic analyser is often given the role of arbitrator in the search for that elusive system bug. 展開(kāi)
