I'm using a TB on a 350Mhz video amplifier 6xRGB , and discovered that
the Video DistAmp was clipping the 10Mhz from the TB.
I used a 10dB attenuator on the TB signal (6dB would have been better) ,

Hi Vlad,
Before we get to your phase noise question...
Your plots ALTINEX-DA-F.png ALTINEX-DA-T.png look odd and the plot
ALTINEX-DA.png shows massive amount of glitches. You must make sure that the
frequency and the phase plots look nice before doing an ADEV plot. In this
case there's
Tom,
I agree that spikes looks weird. Looking for the raw data, I see its
fluctuate from 9.99958E+6 to 1.49E+7
And here how its spread:
#occurr. / FREQ

1 +9.99980E+6

I know some manufacturers use pot core transformers on the output signal.
HP does it for sure. Any vibration or shock transforms right into the
phase error of the signal. IMO, those distribution amps should be avoided
as any level of shock or vibration will contribute to jitter.

From time to time this subject rises again, so i´m sending these links:
