[time-nuts] TimeLab and Wine: was Re: New 5370A

2015-05-14 Thread Bob Stewart
Hi Chuck, I've renamed this thread, and expect it to die quickly.  I have a bunch of things running on my Linux system, so I see a lot of interactions that probably don't happen to others.  One thing is that Timelab doesn't like to come up properly under Wine.  For some reason, it mostly comes

Hi Magnus, Would the 5335A have the same sort of clock noise that I'm seeing on the 5370?  I see it when testing on both the 5335A and the 5370A.  I'm setting up a new test as follows:  Internal 5370A clock, PPS from GPSDO to arm input, PRS45A to start input, and a 6 ft piece of RG-58 from

Might look at this: http://qulsar.com/Products/Managed_Timing_Engines/MTE_Board_P6X.html It has PTP, sNTP, comes with a TCXO, OCXO as an option or bring your own oscillator through the 40 pin connector. Link On May 12, 2015, at 10:11 AM, Mark Spencer m...@alignedsolutions.com wrote: Hi

Hi One of the (many) nice thing(s) about TimeLab is that you can run multiple plots on the same data. Often when you see wiggles in one plot, looking at another plot can help you figure out what is going on. The “best guess” when you see wiggles on the left side, is a spur or beat note. Bob

Hi Bob, The beat note idea occurred to me, as well.  I see the disturbance in the force when using the internal clock (10811) of the 5370A, as well as when using the 10811 from the 5335A as the reference.    But, if this were the case, I would think it would be a well known phenomenon.
