No; per year. The 10811(D?) in a late-model 8662A I owned a few years ago was a serious outlier. If I remember correctly, it was about 3E-10 off after being left on for a year. I'll never find the notes I kept on it now, but it was definitely better than 1E-9.
1E-7 adjustment precision, if that's what they were aiming for, was nowhere near adequate for the 10811 series. -- john, KE5FX > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Rick Karlquist > Sent: Friday, December 29, 2006 12:00 PM > To: Discussion of precise time and frequency measurement > Cc: Discussion of precise time and frequency measurement > Subject: Re: [time-nuts] HP 5345A > > > John Miles wrote: > > There's no manual fine-tuning adjustment on the 10811A, which > is something > > I've always found strange.
