Re: [time-nuts] Raw phase data of super-5065

Hi Adrian, as you know, to get real data up to 100K sec range, you should acquire at least 500K 1M sec. I say this from my personal experience. Soon I will have my 30 days run for both the A and B version of the HP5065. Very interesting the response of the GPSDO in the range 1 to

Hi With ADEV, you really need something closer to 100X your tau to get accurate data. The utter impossibility of doing this for long Tau is what has driven the development of other evaluation methods. Bob > On Jun 8, 2018, at 10:36 AM, tim...@timeok.it wrote: > > > Hi Adrian, > as you

Hi Having run tens of thousands of standards on these sorts of tests … the one that is more temperature / pressure sensitive *will* show up as having worse long term stability. 1) If your environment swings +/- 1C over 48 hours. 2) If unit A is 1 ppb 0 to 50 ( = 20 ppt / C) 3) If unit B is

Hi, This test requires that the two Rubidiun be installed in the same cabinet so they are subject to the same temperature and atmospheric pressure. Acquisitions were made simultaneously.To confirm the data collected, the same test was repeated in another site with two different

Hi Ok, so this question should not come as a great surprise: Does one of the 5065’s have about 3X the temperature sensitivity of the other? ( or pressure or humidity ). Bob > On Jun 8, 2018, at 8:05 AM, tim...@timeok.it wrote: > > > Here a ten days simultaneously run of the A and B
