Operation of Noise Checker
If the one-sided F testing for 95 % reliability is performed on these results and the
calculated Variance Ratio is less than 1.4, the population A (Reference), where the
input switch is OFF, and the population B (Target), where the input switch is ON,
are deemed to be same. That means the noise level of the Target that includes
your measurement environment is considered to be the same as that of Reference.
