Hi Dave --
I should clarify -- this UI is just a character-based menu system using
a dumb terminal program. The code is implemented within the Arduino.
It's written in the somewhat nonstandard C/C++ used by the Arduino IDE.
This morning I'm going to add a "TODO-UI" file to the git repositor
John,
In what language is the GUI written? I might be able to help on that,
or other parts of the software, if someone else hasn't yet volunteered.

Whilst its the highest resolution HP/Agilent/Keysight general purpose counter,
one of the Acquiris timestamping instruments specifies 5ps noise.Whilst no
detailed circuit schematics are publicly available, the datasheet says just
enough to allow me to figure out how they do it.Your timesta
Thanks, Bruce, I'll update the web page to reference the 53230A as the
best resolution device currently available.

I might be able to add support to Lady Heather.Lady Heather does have code
for calculating and displaying ADEV, HDEV, MDEV, and TDEV (it came from
Timelab). Also has data logging capabilities. And can also calculate FFTs of
the data. It can already read Timelab .TIM files.

There is an application note or similar on the 53230A that indicates that
the single shot noise for time interval measurement is typically about 13ps
or so.

Thanks, Andrew. Yes, it is weird how the Arduino folks choose what
capabilities to expose on the board. From some testing I did, it seems
that the Arduino handles the 100 kHz interrupt rate without too much
strain -- it became a bigger issue at 250 kHz or above -- but the timers
would have be

1-2ps rms single shot noise timestamping is feasible with embedded (occurs as
part of the interpolation process) interpolator calibration. Only calibration
of the differential delay between channels is required, as is required by all
such instruments.
However the cost for such a timestamping cou
Nice work!
On the website in the introduction you mention 22ps single-shot
time-stamping on the 5370A/B.
I think it's well established that the 53230A does about 11-12 ps for
time-intervals, which corresponds to about 9 ps single-channel. see for
example:

Fantastic John - well done! Yes, I'll definitely put an order in as soon
as possible.

That TI TDC7200 really is a nice part.
Neat project! Will buy . Two thumbs up.
