Yup, I agree.
I wish I did have one of those TSC5120A's!
Or "at least" an E5052A/B.

One way to evaluate the merits of various oscillator circuits would be
to build an example of each and then measure their phase noise and ADEV.
To keep the number of variables and costs down all oscillators should
use the same 10MHz fundamental crystal.
The oscillators should not be enclosed in their own oven, however an
enclosure with a long thermal time constant can be used.
The oscillator output should be +7dBm into 50 ohms.
No EFC and probably no trimmer cap (however this requires that a
TSC5120A or similar be used to measure the ADEVand phase noise).
Power supply should be standardised at +12V.
