If the example you gave followed those rules, then there would have been no need to mention the 1 dB accuracy of microwave network analyzers. Even by the rules you now introduce, if the analyzer measures 2.01 and the spec says 2 max, there's a problem, but still you argue with your customer that 2.01 is as good as 1.99. If the criteria are agreed upon and that criteria says there is to be a maximum measurement of 2, why do you argue? It makes as much sense as bringing an example where measurement uncertainty is ignored into a discussion of accuracy, precision and resolution. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
