COVER STORY

TEST INSTRUMENTS
T&MW Evaluates Four 6 1/2-digit DMMs
Although 6 1/2-digit DMMs may seem similar, our evaluations show they differ in features and capabilities.
Bradley J. Thompson, Contributing Technical Editor


FEATURES

PC-BASED ATE
Upgrading an IC Tester Cuts Test Time

Using a PC plug-in card, writing new drivers, and using IEEE 488 triggering reduced test time while improving test coverage.
