[GPS_Standard] GPSDO PLL Version 0.13 available

[Bob Stewart]

The code with the state machines is no longer marked as "Experimental", and is now the mainstream version.  I have left Version 0.8 up, but it will be moved to Archives shortly.  There were no versions released between 0.8 and 0.13.  These were internal versions created to help me checkpoint changes.

I've just put up Version 0.13.  I have added a 15 minutes timer from the time it senses best solution (DAC has moved in both directions) until it switches to the larger state machine.  I have reduced the L Parameter from 0x60 to 0x50.  I fixed the bad "ORG" at the help menu, and did the usual housekeeping issues related to cleaning up dead code and comments.

I think this was my last major update to the code.  There is still a fair amount of work to do before it can really be considered a 1.0 release.  I am considering putting an AGC on the step size of the DAC when it is unlocked, but we'll see.  It would still only step by 0x01 when in locked mode if I do.

I finally have a Rubidium Standard to judge the operation of my code by.  And like the proverbial man with two clocks, it is not certain which one of them keeps the correct time.  They are very very close.  By this I mean that it often takes 30 seconds or more for the phase difference between the Rb standard and the GPSDO to change by 1ns.  My next task may just be to take a break from this and get my (clone) Agilent 82357B GPIB adapter working so I can do some decent automated measurements, instead of watching the clock and counting the seconds.
