Bill,
As I recall it, it has a 400 kS/s rate.
Undersampling as it is, if properly used, it is a marvelous tool.
The TDR capability had such a live component to it that I miss in newer
(but butter calibrated) systems.
No wonder I have a system myself these days.
The one thing I would love to
That reminds me -- years ago I cleaned up, corrected, and annotated a
copy of the HP 10544 schematic. I dug it up and just posted it to
Didier's site (http://www.ko4bb.com/manuals/). When it comes off
quarantine, you can find it by searching for:
HP 10544A schematic corrected and
The counter is in TIME MODE. And simple calculation could transform it
to frequency as necessary. For example:
1/(350.50824*10^-9)
2852999.97512184021693755330
OR
1/0.00350508240900
2852999.96779619226350692058
Which is pretty close to my DDS VFO freq. value [2853000]
I switch

The quarantine is officially over (for this week :)
Thanks for the uploads

PS: I am now trying to move the manuals and equipment specific docs out of the

convenient for those who are only interested in
Hi
Either the output data is with the counter set to time mode (and it’s in 100’s
of ns) or you have it
set to frequency mode and have a very stable system.

PHK,
I ran across this wonderful shaker table experiment and concluded that
post-processing would always be better than playing moving antenna games.

Hi Vlad,
Here are some comments. Please read carefully.
Look at your data and notice that every reading is the same 3.505082408E-7,
except one is 3.505082409E-7. That's not going to give you very good plots at
all. Also you're not going to get much information out an ADEV tool with just
13
I switch counter to TIME MODE, because ADEV1 utility using times, not
frequency:
No. ADEV1 expects phase. Not time, not period, not frequency.
Here is from documentation:
Adev1 works on everything from pendulum clocks to hydrogen masers. The
only restrictions are that the data must be
Thank you very much Didier for your wonderful site and thank you again
Charles for your precious schematic. Finally i'm able to understand
something more!
Ciao!
