Can I measure a duty cycle & frequency of PWM signal with PXI-6534?

Can I measure a duty cycle & frequency of PWM signal with PXI-6534?
 
Counter is usually used to measure the pulse width but there's no example using PXI-6534 to measure that.
 
So I wonder PXI-6534 can measure the pulse width.
 
If PXI-6534 can do that, can I have an example file?

Hello labviewbeginer,

I don't know of any way to directly measure duty cycle or frequency using the digital I/O lines on the 6534.  Because the 6534 does not have any counters, there doesn't appear to be a direct way to use the board to measure frequency or duty cycle.  However, you can acquire the PWM waveform and determine the duty cycle and frequency in software.
