The accuracy for duty cycle and pulse width is based on a 5 V square wave input
into the DC 5 V range. For AC coupling, the duty cycle range can be measured
within 5% to 95% for signal frequency > 20 Hz.
Positive or negative pulse width must be greater than 10 μs and the range of
[2]
duty cycle should be considered. The range of pulse width is determined by the
frequency of the signal.
