1) The magnetic noise is normal distributed and can be assumed as nearly independent to frequency without sampling noise
or digital noise effects. The typical value represents a the rms-value and corresponds therefore to a 1 σ probability of
normal distribution. Consequently a 3 σ value corresponds to 99.7% probability of appearance.
2) Not subject to production test, verified by design/characterization.
