[GPS_Standard] GPSstd_PLL Version 1.0 released

[Bob Stewart]

This post is to let everyone know that I'm finally releasing a Version 1.0, which is essentially a cleaned up version 0.24.  I've spent the past few weeks checking usability and functionality, and looking for things that got lost, like the top and bottom hardlimits.  I've abandoned the fast PLL that I was working on, as well.  As others pointed out, there was just not enough information to make it work reliably.  I've added a new "U" parameter.  It works just like the "L" (lock) parameter, except it sets the number of seconds below which the system will go to unlock.  I've also changed the mechanism to go into lock.  After adding a voltage divider to the EFC line in my GPSDO, I discovered that it's not enough to call it locked when the DAC step size goes to "1".  So, now the lock state is solely controlled by the "L" and "U" parameters.  I also fixed a bug in the "holdover" code.
