I am working with cRIO .. I am not able to understand how does it actually use ni-9205 to read analog input. Means i am sending analog data and i am getting directly the voltage over the front panel but what i accepted was PWM values. Why so and How .

Is it converted by ni-9205 first to adc and than to required value .

I believe the 9205 is a SAR module.

 

Can you show us what you expect the signal to look like and what you're actually getting. What is the frequency of the PWM?
