residual phase-noise graphs/datasheet?

[aewallin]

I would be interested in the residual phase-noise performance of the distribution amplifier at various frequencies.

In particular for 10 MHz distribution I and others have published a few comparison-graphs:

It would be interesting to see where the Clocker fits in these graphs.
thanks!

Out of curiosity, did anyone ever get around to measuring this?

Hi,

I finally found dome time to measure the clockers residual phase and AM noise. As a reference I used a 100MHz Wenzel Quartz, that is phaselocked to a 10MHz Wenzel blue top.

Blue trace: 100MHz versus the same 100MHz as a reference measurement.

Pink trace: 100MHz vs Clockers 100 MHz Output (residual noise from clocker)

PN:

AM:

Our measurement shows no AM zu PM conversion.

and the MDEV:

The Performance is en par with other high performance distribution amps. The higher noise below 10Hz is mostly due to temperature effects (Roberts suggestion that I agree with)

Is there any interest to repeat the measurement with temperature logging or other frequencies?

Lovely data, thanks for posting! Looks pretty darn close to the datasheet as well
