---------------End of Original Message----------------- Paul: The following isn't OFFICIAL, just my perspective on your question. But, it may help to better frame the terms of the inquiry. An "RF measurement device" could be: 1. A device which intentionally generates electromagnetic energy to evaluate the physical condition of a material. 2. A device which intentionally generates electromagnetic energy to evaluate the presence, motion or proximity of a material. 3. A device which measures the quality or magnitude of electromagnetic energy. A "radio communication device" is a device which facilitates the transfer of information by electromagnetic means. There's obviously some overlap of the categories. A field strength meter may also derive some information from an observed signal. A proximity sensor may derive some information about the characteristics of the target's motion and composition. A communication receiver could provide an indication of the signal's strength. Maybe the best distinction is in the use of the device; is it being used to observe a condition or is it being used to transfer information? Hmmm, sort of like how your feelings about a shotgun depend on which end is pointed toward you. -------------------------- Ed Price ed.pr...@cubic.com Electromagnetic Compatibility Lab Cubic Defense Systems San Diego, CA.
