Gary, Lots of ways to do it. There are GUI tools; command line tools, in C or Python or Matlab.
But to start with I highly recommend using John's TimeLab: http://www.ke5fx.com/timelab/readme.htm Here's a sample 1PPS phase (time interval error) data file (from a hp 53132A): http://leapsecond.com/pages/MG1613S/log167.txt Or here's the same file in a more standard format: http://leapsecond.com/pages/MG1613S/log167.dat Use TimeLab->File->Import ASCII. If you can't figure out the boxes let us know. Then all you do is type p or f or a or t to cycle through phase, frequency, ADEV or TDEV plots. You will see something like this: http://leapsecond.com/pages/MG1613S/log167-phase.gif http://leapsecond.com/pages/MG1613S/log167-freq.gif http://leapsecond.com/pages/MG1613S/log167-adev.gif http://leapsecond.com/pages/MG1613S/log167-tdev.gif /tvb ----- Original Message ----- From: "Gary E.

I have a lot of logs of PPS offset data. Basically system clock time and PPS offset pairs. Does it make sense to turn this data into an Allan Deviation plot? If so, does anyone have a script or program to prepare the data for gnuplot? TIA. RGDS GARY --------------------------------------------------------------------------- Gary E.
