THE ONLY EXPERT GUIDE TO DESIGNING AND IMPLEMENTING CUSTOM TEST SYSTEMS
More and more engineers now face the challenges of electronic testing(and those challenges are becoming more complex each year. In Test System Design: A Systematic Approach, three expert testing professionals offers start-to-finish best practices for designing, developing, and implementing custom test systems. Ideal for both engineers who are creating test systems and those contracting the responsibility to third parties, this book covers the entire system lifecycle, from planning to upgrades, and beyond.
Discover proven techniques for evaluating your testing requirements, eliminating redundant tests, and determining exactly which equipment you really need. Compare your options for sourcing test equipment, and learn how to maximize the value of every supplier relationship. Learn better solutions for documenting your test systems, training your operators, streamlining your maintenance programs, and more. No matter what your testing challenges are, Test System Design is your comprehensive resource for achieving them faster and more cost effectively.
