I did a lot of testing of 53132A counters a while back to research how well the interpolators worked and to measure the interference when CH1 gets too close to CH2. There was some discussion on the list about this at the time. For the context, see: https://www.febo.com/pipermail/time-nuts/2014-April/084670.html For the plots, see: http://leapsecond.com/pages/53132/ A good paper to read about the trouble when DUT is close (or "equal" to REF) is: http://literature.cdn.keysight.com/litweb/pdf/5990-9189EN.pdf "Isolating Frequency Measurement Error and Sourcing Frequency Error near the Reference Frequency Harmonics" See also: https://www.febo.com/pipermail/time-nuts/2012-October/070737.html /tvb _______________________________________________ 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.
