I figure you're both wrong. If the measuring instrument is no better than 1 dB absolute, you can't expect to do it - a flat line measurement could represent an actual + or - 1 db, the limit of the spec. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
