As in GPS, for instance, where chip rate is related to carrier frequency.
Exactly. Very strict integer
Hi Jim,
Leapfrog navigation has been discussed for mars navigation.

Just realized that the gravity potential detuning needs to be adapted to
the mars orbit and gravity field. Which also makes

No, it doesnt.

Ah ha! That explains the changing numbers I see on the 5370B (jitter), and
explains why I see no change on the scope other than the jitter. Reading
the manual, I don't see any clear explanation like what you just gave me. I
see my mistake in manual interpretation but not until after reading
With a lot of help from some of the other time-nuts, I've been working
on a follow-on to the TADD-1. Progress has been non-existent for the

One way of reducing the effective noise/jitter on the PPS signal when
using it with the 5370 to measure the instability of a source with
respect to the Thunderbolt is to use the PPS to ARM the 5370 whilst the
10MHz from the thunderbolt starts the 5370 and the source (or a

Question for David Patridge:
I was looking over your design of the CMOS Frequency Divider 2,
schematic date 2008-07-10.
Have you performed a jitter test on your design ?

In a partial answer to my own question, and information from a post dated 29
May 2007 by Peter Carran:
FS5951 is a temperature controlled crystal oscillator.
My shortform Cathodon catalogue describes it as follows:
Freq stability: 0.1x10-6 0 to 60C
Osc supply: 5 volts 300 mW
Oven
I don't have the equipment to do that test, however a number of folks who
did order a kit frequent this list and may have done such tests, but haven't
owned up to the results.
Sorry
Dave
