New for August 2016: design of experiments, or "DOE" (say dee-oh-ee) is a means toward optimizing variables to produce a more consistent product. Because microwave engineering resides more in the analog world than the digital world, it pays to know what design of experiments is all about. Chances are that some day your boss will ask you to perform a DOE, so pay attention.
Below is a video concerning DOE, from Keysight. The narrator is Jack Sifri. DOE can be used in the design process to maximize your chances of first-pass success, as Jack explains. It can also be used to troubleshoot hardware that is already in production, even if all of the design files and designers are dead and buried, like when you are working on a thirty-year old product such as HARM missile. DOE will allow you to quickly locate the sources of misery and defeat them, without having to examine every combination of parameters in a multi-variable system. As Jack points out, it saves time and money.
