fpga pwm signal falling edge problem

Hi all,

 

I have a problem with my pwm signal. I generate pwm signal with NI 9475 on cRio.

Hi gulyvz,

 

according to the manual the NI9475 is a sourcing DO module.

 

I have a problem…

What's the problem? Blurry images?

 

I guess the picture shows the voltage vs. time and you speak about the falling edges: is there any capacitor (or low pass) connected at the DO?

What did you connect to the module? Can you supply schematics?

 

Best regards,
GerdW

Hi GerdW,

 

I have a problem with square signal falling edge. I want to generate square signal which duty cycle adjustable.

 

I hope it will be clear.

 

Thanks
