Martyn:
Two things to be aware of:
Injection Locking and loop dynamics.
Injection Locking:
Injection locking can be observed by manually moving one oscillator
frequency closer to the other frequency.
If one oscillator jumps to the other frequency then more isolation may
be needed.
Loop Dynam
For Frequency, Phase, Time and Distance I use:
(delta frequency/frequency)=
(delta phase/phase)=
-(delta time/time)=
-(delta distance/distance)
This is shown on page 20.16 of Electronic Instrument Handbook, second
edition
by Clyde F. Coombs.
It is a good reference to have available.
I looked
time-nuts members:
What are some signal generators for ATE test?
Requirements:
100MHz to >=10GHz (higher would be better)
Settling time less than 1mS
Reasonable phase noise
Cost, less than mortgaging a house.:)
Just a single tone that can be moved reasonably fast.
IQ modulation not required

It has been a number of years since I have used a HP3048A-HP11848A
system.
I have two HP11848A test sets and a spare PC or two with NI GPIB cards

It looks like this will be much easier to use
Time nuts:
Here is a prediction of how it could go on the WWVB chip situation.
Moors law will under price the custom chip price in small (and even
large) volumes.
It already has.

A WWVB receiver can now be done on an Arduino microprocessor with a
lit
Here is a related Arduino project.

This is where I get my Arduino boards.
I like the 32 bit Arduino processor for some applications.
