They do it pretty much the same way everybody else makes the same
sort of oscillators. Design, build, tune / select, test, re-tune/ select, re-test.
The amount of test / tune depends enormously on what level of oscillator
is being made. > 80% of the volume shipped gets relatively less effort than
the other 20%.
