very inclusive

Brilliant job on this.

From someone that spent their first five years of their engineering career testing relays, this is a really good representation of how things should be done, and I am glad that you guys stuck to your guns on how to test and not modify settings. Also to not focus on the software and testing suites that do “the work” but instead expecting people to learn the fundamentals to it is the best course of action. We should have this expectation in the industry, but it has become convenient to “rote teach” techs.

Wish you all luck, and I hope more people can benefit from this. I spent my formative years being thrown to the wolves to learn this. It is nice to see this and the books done in a way that can give someone a background before they get pushed into testing more and more complex devices. Hopefully people can get this info and run with it with great success.

Thanks Chris, for another great class that helps review information that you don’t always use all the time.

Thank you Chris for an excellent course. Always very helpful to get other perspectives on testing philosophy and procedures, especially in the logic realm!
