Hi Charles,
My Z3805A are usually in the 1-4us range. I was pleasantly surprised to see the nanoseconds! I must ask, do you have the later Z3805A with the MTI oscillator? Alll mine have the older 10811 Double oven. -marki -----Original Message----- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Charles P.

I don't have a Z3815A and don't know how they are supposed to behave, but when the 24 hour holdover prediction of my Z3805A goes below 1 nS it registers in pS.
