Table 7-11 Duty cycle and pulse width specifications
Function
Notes for duty cycle specifications:
1 The accuracy for duty cycle and pulse width is based on a 5 V square wave input into the DC 5 V range.
2 For AC coupling, the duty cycle range can be measured for signal frequency > 20 Hz.
Pulse width
Notes for pulse width specifications:
1 The accuracy for duty cycle and pulse width is based on a 5 V square wave input into the DC 5 V range.
2 Positive or negative pulse width must be greater than 10 µs and the range of duty cycle should be considered. The range
of pulse width is determined by the frequency of the signal.
