The benefit is that I can de-correlate the reference oscillator noise,

I have just started doing this, so this is really my first sloppy
measurements for you to see where I am heading.
I expect John to chime
Fellow time-nuts,
I have borrowed Björn's FTS1200 and OSA8600 and that complements my own
OSA8600 and OSA8601.
I use a HP5087A and one of the OSA8600 as references, such that I can
cross-correlate out the reference oscillators. I'm still not quite
satisfied just yet, so I may need to work
Hi Magnus;
Very Nice

Thanks!
Tom has very kindly provided some seriously good cables, which is being
used for these measures.
The TimePod comes straight out of the hands of the usual suspect John
Miles, as part of out travel to Boulder.
Magnus, this is very cool. Can you describe your cross-correlation
setup with the Time-Pod? I'd like to play with it here and compare notes.

1. Unscrew the hardwire jumpers on the input side of the TimePod.
2. Hook up two low
Bottom line, the large low-frequency spurs in the FTS plot at 1.4 and 2.9
Hz
will be caused by one of these conditions:
1) A problem with the reference source(s)
2) A problem with the FTS oscillator itself
3) A normal characteristic of the FTS oscillator (maybe its spur specs
weren't
