Dave, No, you'll never be the equal of TFlan as a curmugeon, but we all are entitled to try. :-)
I also am guilty of using that term "frequency analyzer," and never thought anything about it, since I figured the machine was doing some kind of analysis of a shaft. GS has been calling them by that term ever since I can remember. Good to have an EE explain the definition and it certainly makes sense to this retired copy guy. Now, is the GS machine an Analyzer because it uses dual strain gauges, a load cell and sensor to get the number? I suspect not by your definition.
