Hi
….. a little elaboration …..
If you *don’t* terminate the main distribution line, it effectively acts as a
great big antenna. It
floods the lab area (or production floor or building …) with 10 MHz. I
unfortunately have a lot
of empirical data to back this up.
It’s also worth using a
I have a large box of 8140 pods (well, I call them "taps"). They are
quite handy for stringing distribution points around a large room,
provided ultimate phase noise performance isn't required.
You *don't* need an 8140 main box to use these. All the 8140 does is
put 12V DC bias on its
Good work on the project, Julien. I have a couple of the 8140 distribution
amps, one of which I use in my shop. Instead of buying the line taps that
are supposed to be used with the 8140, I just disabled the 12V riding on the
output signal coming out of the amp.
I have another unit as a

You could always email Ken Senior at NRL and ask him.

CANVAS is apparently northern hemisphere specific.
I just asked and was allowed to download CANVAS including source code

Slightly edited down from my blog, if you want the full thing with

I've mentioned a bunch of times on the time-nuts list that I'm quite
fond of the Spectracom 8140 system for frequency distribution. For those
not familiar with it, it's
