It is easy to add a JTAG programming header to the TBolt display sold by fluke.l and others that are based on my design. The software is already written for the TBolt, the code is open source (in C), somewhat documented and available, the tools are free and the JTAG adapter is only $20. The

[time-nuts] Timing performance of servers

2012-10-24 Thread Magnus Danielson
Fellow time-nuts, When spending time on a conference last week, I heard one interesting comment that they lost data due to bad timing on their Windows servers. Now, I know that the standard Windows uses SNTP in order to achieve the goal of having the timing of the machines sufficiently

Dear Mangus, I will allow myself to share a comment on your thread. Timing on windows servers is not one of their plausible strengths. It was clearly pointed out during the SIM conference last week at CENAM. In fact there was an interesting discussion about the drawbacks when using NTP

Hello, recently I couldn't resist to acquire one of these Racal MA259 units with a SA 500 crystal oscillator which was designed by Sulzer. What a beautiful piece of ancient high precision laboratory gear! Well, it wasn't claimed to still meet the specifications, but it was at least in a

Hello Paul, I guess you tested it at 57 kHz? Were you able to get it to work with your simulator at the normal frequency? Does anyone have details on the test mode? I just picked up $3 worth. Regards, Tom - Original Message - From: paul swed paulsw...@gmail.com To: Discussion

li...@rtty.us said: The gotcha with the DDS is phase truncation. That pretty much trashes the ADEV. Thanks. How should I think about the output of a DDS? Lets assume I'm interested in the frequency domain where the error is measured in phase noise. For a DDS, I think they are spurs.

Just a FYI here, using Dave's logging program, I found large errors in NTP when the antivirus did its thing. I don't know if it was due to CPU activity interfering with NTP or the cabinet heating up when the antivirus was running. -Original Message- From: David J Taylor

A number of people have asked for information about the VFD display/key option on the 58503A. I'll take one apart next week, but meanwhile here are some photos for those of you who have not seen what the display looks like: http://www.leapsecond.com/museum/58503a-01/ /tvb
