isolated distribution amp
Hi Charles,
Thanks a bunch for the comments and the article reprints. This is just what
I was looking for to get started on my distribution amplifier.
Regards...Bill

Hi Dave,
That's exactly the approach I'm going to use. Outputs that go to instruments
that might see the low noise and then outputs that go to devices that aren't
phase noise sensitive like counters, scopes, pulse generators and others.

Hi Martyn,
I looked at the specifications. Very nice indeed!!
I will contact you off list for more info...Bill

residual phase noise will contribute lower additive noise to
another device. I think additive phase is a more apt description of the noise
within a system being used, rather than reference to the measurement system of
a single device.
Oh boy, I hope I didn't open up a can of worms.

Hi Luciano,
Thanks for sharing that data. Do you have a link to the NIST distribution
amplifier?
When you're ready I hope you'll share more data on your MDT123 design.
Regards...Bill

What's the latest opinion (data) on available low additive phase noise 10
MHz amplifiers for 10 MHz distribution?
Regards and thanks.Bill

Hi
For any “real world
and
do some prototyping and noise testing and see what I come up with.

Hi Perrier,
Thanks, I would like the documents.
I have a HP 3586B and its sensitivity is right on for the 20 Hz and 400 Hz
bands but is about 30 dB low for the 3100 Hz band.
I have manuals but have not found the fault. Do you have suggestions?
Regards,
Bill

connector. I’ve been doing this for 40 years and I still mess
it up on a regular basis. We also seem to get it wrong from time to time
when we lay out connector connections on pc boards, but that’s another
story altogether …..

Hi Bob and group,
Where are you obtaining Satstat and what windoze version will it work on? XP,
W7 32 or 64 bit? XP I guess?
