Re: [time-nuts] Z3805 two frequency maxima

...and I found a very interesting article on that topic: http://www.micrel.com/_PDF/App-Notes/clk/PAN1202291%20-%20AFM%20Period%20Jitter.pdf It's written by Eddy van Keulen (Micrel): Relation between Harmonics and Deterministic Jitter. His approach is the assumption, that frequency

Re: [time-nuts] Best phase detector / mixer for 100MHz?

Hi Bruce, The equivalent phase noise (measured in dBc/Hz) is essentially independent of the sample size. The dBc/Hz normalization is based on this (also the sample rate). While the sample rate sample size = FFT Bin size (resolution or filter band width) is used to get the required

[time-nuts] Stanford Research SR620

Hi Everyone, I'm selling my SR620 and thought to offer it here first before the eBay. The only problem I know about is an error 3 on power up. This equates to the battery backed up RAM not holding its load. The battery checks good so it's probably the RAM chip itself. You can then select a

[time-nuts] Z3805 incident

When looking at the PPS TI vs. time curve today I felt kind of appalled - a big incident peak (not an outlier) on the curve! See picture. What happened to my Z3805? Any idea? No entry in the error log, the staus log says 2012-11-28 10:01:30: The Smartclock Status has changed to LOC 2012-11-28

[time-nuts] Termination talk

I was going to post an anecdote about termination to the list and then thought that the piece would make a great column. It did. My magazine featured it in one of its daily mailings. If you want to check it out: http://www.ecnmag.com/blogs/2012/11/long-lines-pcb Simon   Engineering is the art

Re: [time-nuts] Z3805 two frequency maxima

Hi The gotcha there is that most oscillators have a low pass filter on the output. There is an observable 5 MHz component, but the 15 MHz is much further down. The synthesis is useful. It's just tough to convince anybody it's correct when they can't see the 15 MHz. Bob On Nov 28, 2012, at

[time-nuts] Poor termination effects?

I live in the San Francisco bay area. You may recall that back in 1989 we had a big earthquake that did a lot of damage. The epicenter was near Loma Prieta, which became the name for this earthquake. That is about 60 miles south of San Francisco, yet a lot of the bad damage occurred there, at

Re: [time-nuts] Poor termination effects?

I am pretty sure you are right on the mark there. I made a habit of listening to the tone modulated seismic transmitters in southern California and with experience, they definitely sounded like you would expect if a source was reflecting off of various impedance discontinuities in the crust which
