Because there are 10 measurements total, repetitions on X1 will be 4, repetitions on X2 will be 4,
and repetitions on X3 will be 2. Using the default settling time (500 µs) and the first notch
frequency figured earlier (100 Hz), the sum of the above equations gives a total measurement
time of 427511 µs (427.511 ms). Therefore, a practical scan rate for this setup would be 500 ms.
