And Hal- what about the pcb layout for Bruce's 74CX version? Had time
to look at it yet?
It fell through the cracks when I got interested in something else.
Is anybody really interested in that board? If so, please send me a
reminder about the schematic.
There have been lots of ideas

Hi Bruce, I for one would like to get the completed circuit seeing as I
started the whole thing off and was just getting ready to maybe do a copy of
the HP unit.

The 80 meter run will be first, followed immediately by the 40 meter run and
ending with the 160 meter run.
80 meter frequency will be near 355 Hz

Although I use and favor gnome as my desktop, I've been using kde's kst
plotting package. It is not bad, which for me, discussing a software
package, is an above average endorsement.
Incidentally, I've found that it is important to be quite careful with your

picosecond resolution in an IEEE 64-bit float.

I came across an old article on the Delay Line Discriminator for Phase Noise
Measurements (Microwave Journal 1983).
I don't think the theory has changed much since then :-)

Dear all,
I have developed a theory of the delay line. Using the
Laplace transform of the phase, mathematics is amazingly simple.

I used a 100k sample average which yields (IIRC) 200 femtosecond
resolution in the 5370B, and for each run checked the min, max, and
standard deviation statistics to make sure nothing goofy was going on
Standard deviation for a run like that on my 5370B is typically 30 to 40ps.
