![]() ![]() Thrifty Test Equipment Vector Network Analyzer ![]() Identifying issues early allows maximum flexibility to experiment and provides sufficient time to make cost-effective changes before a design is frozen and difficult to change. Although the thrifty method is mainly used to compare results before and after implementing a fix (not meeting a specification limit), with some experience it can also be used in the pre-qualification development stage early in the design cycle to identify potential issues before formal lab testing. 1 This article offers some other test equipment options that have different capabilities and which can be even less costly. There are several excellent resources for troubleshooting methods and building a low-cost EMC toolkit. But inexpensive test equipment and procedures (let’s call them thrifty methods) used for helping to solve these EMC issues outside an EMC lab are very desirable especially if no in-house EMC facilities are readily available. Obtaining a cost-effective solution to these EMC issues may be time consuming, and many EMC labs can be fully booked or have limited availability, have long lead times, or involve significant costs. Issues related to electromagnetic compatibility (EMC) are often identified during qualification testing in an accredited EMC test lab which typically occurs late in the product design cycle.
