[SI-LIST] Do you ever measure any of the things you model?

I notice that you all are most concerned with your model.
Now by the scientific method, you have a hypothetical solution, produced by
your model.
The next step is to EVALUATE the result.
That is done with a very good scope.
No one ever seems to comment on this, leading me to suspect you only model.
You know they did that with the Hubble space telescope.
That technique produced one of the most expensive service calls in history.
Once modeled, they should have TESTED the thing.
Testing goes hand in hand with modeling, on the assumption that the model is
incomplete.
No measurement, saves lots of time. Any naive manager just loves to save test
time.
"Our models are perfect, you know" says he. ( He missed point of Scientific
method, entirely)
So what kind of scope and what kind of probing technique do you use?
How do you ground your probe setup to the PCB, as a place to start?
How much noise on the ground??
What is the exact construction of the probe interface to the PCB?
This all counts, in high performance probing.
