Here I open again the subject under a new cover. I think my question, and underlying honest intend of use, was not clear in my previous writing. Its why I comeback on the subject 'what is a Radio Frequency (RF) measurement device'. Please read on, do not answer here.
Later, when I have that definition, and only when I have that, I will be able to comeback on the initial subject 'when do I need a license'. Please do not answer here on this now, read on. Let me try to give a clear overview and clarify this: The intend of this writing is NOT (NOWAY, BY NO MEAN) to try to use any RF measurement tool as a disturbing intentional radiator or in a outlawed signal capture mode. The intend is NOT to couple by any mean, and in such a way, a measurement tool in order to be able to disturb or monitor specific private or official outside world RF signals. The intend is to use it as a real measurement tool (like for EMC). The intend is to use existing or home made tools as measurement devices (for instance for some pre-compliance tests or alignments). Please don't look for ANY hidden or evident bad intend of use and operation, that's outside the scoop of my question. ------------------------------ Here is the question. Who can give an 'official' definition existing and specified somewhere of: What's a RF measurement tool (and in what aspect is it different from radio communication equipment who govern, I believe, the requirement for a license) or do the meaning of RF measurement tool different from radio communication not exist? In the later case (when not exist), how do you explain the 'radio communication' aspect of a measurement tool who can, for instance, be designed and used as a direct link between the UUT and the equipment? I'm thinking for instance of a RF wave generator to align filters and a oscilloscope to monitor signals. When I push the ball a little more, is any signal processing circuit (like a TTL) then a radio communication device? Honestly I think that a RF measurement device (tool, circuit, equipment) definition must exist but how and where is it defined to be not part of the radio communication aspect? Where are the limits between both? ------------------------------- SIDE NOTE: Thanks to everybody who mailed me previously. There was a lot of good thinking in the comments. I agree with the personal considerations put forward. Thanks on beforhand for your inputs. Best regards,
