HI
Assuming 0.01 Hz at 6 GHz is the resolution, that comes out to 1.6 ppt. That’s
roughly
10X better than the noise level that Mark reported on the FA1. Given that
resolution is not
the same as noise and 10 seconds may well be 10X better than 1 second, it’s not
at all clear
how the two data
Hello everyone,
I’ve resurrected an old and no longer supported implementation of PTP for the
STM32 series of 32-bit microcontrollers.
In a nutshell: the ethernet MAC on these micros has hardware support for packet
time stamping and fine-grained adjustment of a free running timer. ST Micro had
Looked around at specs. I don't know that I can believe .01 HZ at 6
GHz??? Is that approx 10^-11?? even with gpsdo reference and 10 sec
gate.
But even so, there are possibilities for this device. I, too, will have
to downsize my boatanchors someday soon.

I bought the FA-2 and will be comparing it to the TICC and other counters I
have. I’ll probably wire up a better supply for it.

I saw that too a few days ago and was intrigued. It sort of looks like an FA1
with some smarts and a display. I'm also interested in others' experience.

While looking on ebay at the BG7TBL FA1 analyzer I looked on
Perry as you have down sized it is a good opportunity to leverage more
modern options.
I can't speak to the quality/accuracy/value of the $100 units. But
Time-nuts can.
The fact is these things are pretty amazing and consume little power and
generally have modern USB interfaces and software.
I have for sale three HP 5061As
All three have the clock options.
One I obtained from a time nut member and he has run it and it locks and
functions.
I am asking $1200 for this one plus shipping.

The other two both run, but only one locks with the cesium
Hello all,
I searched the old time-nuts archives for TimeLab connection issues with
Tektronix FCA3xxx or Pendulum CNT9x counters.
There are some infos but I am not able to get mine running with TimeLab.
Somewhere here I read that Tom (van Baak) has a FCA3x counter running
with TimeLab, but I
Yo Bubba Dudes!,
While looking on ebay at the BG7TBL FA1 analyzer I looked on the bottom of the
page where other items are advertised an saw ads for the FA-2 Precision
Frequency counter which is sold by multiple vendors in the $115 range.
As I have to down-size It appears to be just what I could
Hi
Assuming Mark’s data is at 10 MHz and 1 second then 0.0002 Hz is 20 ppt. That
number
can be compared directly against data presented for a variety of other devices.
By far the
best way to do the comparison would be to take data over a range of tau’s and
look at the
resulting plot. That way
This would be an interesting compare.
I want to compare the FA1 and the TSA3011 if I am back in office and
have both in my hands...
But I really do not want to buy unnecessary tools... So if someone has
done this it would be nice to read about that.
Mark, do you have also a TICC?
