> Using bench type instrumentation has nothing whatsoever to do with what I'm talking about. At no time did I ever say that my portable device was a substitute for professional test equipment.

Your words, not mine. Without more context (which you didn't provide) it's unreasonable to expect me to understand what you mean (you, in fact, advocate I don't 'read stuff' that isn't actually there) outside of replacing actual test and measurement equipment.
