Hi --
There's some fairly old data about the Octoclock here:
http://www.anderswallin.net/2016/09/ettus-octoclock-distribution-amplifier/
In the shameless plug department, the TADD-1 distribution amplifier from
TAPR:
https://tapr.org/product/tadd-1-rf-distribution-amplifier/
has very good additive noise, and is inexpensive. It has six channels
but two or more boards can be stacked and driven from a common input.
The downside is that it's a kit (through-hole parts).
I compared the additive phase noise of several distribution amps here:
https://www.febo.com/pages/amplifier_phase_noise/
(that data is also fairly old; currently-shipped TADD-1s use a newer
amplifier chip that seems to have a couple of dB better performance).
Best,
John

Hello,
I am building a high-end testbed and trying to decide on a 10 MHz
distribution option. I've used octoclock for other systems and it
'works.' However the datasheet is pretty sparse. Does anyone have
detailed specs (that you measured or from Ettus). I am interested in
the non-GPSDO version since my 10 MHz comes from outside the system
* port-to-port delay variation
* phase noise increase if any (assuming external source)
My other option is
https://endruntechnologies.com/products/distribution/10-MHz-low-phase-noise <https://endruntechnologies.com/products/distribution/10-MHz-low-phase-noise>, which is about 5x more expensive.
Thanks.
