Lady Heather should do the job. It supports using a GPS device as the main
input device and a TICC/counter as an auxiliary input device (/ei= command
line option). Writing a .xml format log file will have all the data. On a
TICC you should connect chA to the 1PPS signal (and optionally the
I really think we're on the same page.
Appendix A in the PRS-10 manual lists a set of recommended divider settings
such that you can select values for the divider to add a bit more or less
frequency offset so that you can bring the 10Mhz Oscillator into lock at
10Mhz regardless of what the Rb
Yes, I have more or less cloned the temperature regulation circuitryand used it
for various heat control circuitry using other/similarsemiconductors that can
handle elevated temperatures.
The basic principle is nothing exotic. It can be found inmany applications all
over the internet.

Hi
Page 19 in the 145190 data sheet sends you off to a bunch of app notes about
designing the rest of the circuit. If the reference frequency used does not
match
what the loop filter is designed for, things will not go well. Spurs and
damping are
both dependent on things matching up.

In Unix there is the "ts" (aka timestamp) command will be a good start as
long as you have newlines (pure NMEA has CRLF at the end of each line but
I've come across devices that use other variations).

Update: I have finished routing the board (placement diagram at

ordered a few prototype PCBs.
After the earlier discussions on the list I've grown sufficiently concerned
about the impact of 1/f converter noise that I have added
One of the GPS modules I'm currently playing with outputs quantization
error data in the NMEA data.
I can capture the NMEA data and the TICC data - this is not a problem.
But I'd really like to be able to capture both datasets in some sort of
time-correlated way, so I can easily post-process the
