Problem to measure 0% and 100% duty cycle of a PWM

[hunan604]

Hi,

I am using counters of USB-6341 to measure duty cycle of PWM just by following the example 'Meas Duty Cycle-Buffered-Finite.vi'. It works almost all the time. However, when the duty cycle of a input pwm is 0 or 100%, the DAQ can't read anything, in another word, it can't measure 0 or 100% duty cycle.

How to modify that?

Thank you very much 🙂
