[1] The range is calculated from {10 μs × frequency × 100%} to {[1 – (10 μs × frequency)] × 100%}. For example, a 1 kHz signal
can be measured from 1% to 99%.
[2] The positive or negative pulse width must be greater than 10 μs. The range of the pulse width is determined by the frequency
of the signal.
