Accuracy ratings for digital displays are commonly specified as a percentage +/- 1 LSD. So given tolerances of +/- 1 dB +/- 1 LSD for the analyzer and +/- 1 dB for the DUT, 2.01 dB is technically within spec. -- john, KE5FX _______________________________________________ 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.
