Hi All, I have been writing again and this month's Technical Tidbit on my website, http://www.dsmith.org , discusses the need to control stray parasitics in tests to avoid error and wasted troubleshooting time. Abstract: It is imperative that test variables be controlled to avoid testing errors when looking for design problems or during compliance tests. Making measurements to characterize the test setup is one way to accomplish this. Using an ESD example, the use of current probes during testing is demonstrated as a way to monitor and control variables in the ESD test setup and equipment. The link to the article is the picture of the experimental test setup at the bottom of the home page at http://emcesd.com .
