If you have an older PC/laptop that can run DOS or WIN98 and has a VESA compatible video BIOS  then you might want to try Lady Heather's Disciplined Oscillator Controller Program (downloadable from the archives).  It has bulilt in support for calculating and graphing the ADEV/OADEV of the PPS and OSC parameters.  Also graphs the PPS and OSC values along with the DAC and TEMP parameters and the satellite count.  Constellation changes are also marked.  The source code is there if you want to modify it for a more modern system.  The distributed version was compiled with Quick C and set up for a 1024x768 screen.

One test you can perform that should give an indication of the location
of the Allan intercept is to:

Ok, thanks for your clear instructions!

My test periods have been much too short, if the Kalman filter learning
takes even days! But with these instructions I'lll get better data for
OCXO vs. LPRO comparison and maybe also the OCXO health.

Ulrich's Plotter is good for this

Hmm. Is that software available somewhere?
No luck with quick Google tour...

Thanks again. Just tested that (runs also with XP DOS mode) and it's
great! Have to set some older laptop for this. It even shows me that the
Kalman filter was still OFF, that information seems to be missing in
tboltmon.

Hi Mark,

Where from could I download this program (Lady Heather....)

Thanks

Hallo Folkert,
Ik zag C, gps en source dus misschien iets voor jou
