Hello,
I have a NI-9472 inserted in the slot 6 of a cDAQ-9189 chassi. I am trying to generate a PWM, however I am facing some difficulties. When in frequencies around 150 Hz, I obtain correctly the pulse train, but as I increase the frequency it looks like the signal takes longer to go to low level.
I tryed to get the waveform with an oscilloscope connected directly to the output of the NI-9472, and the attached images show the situation I have described.
I looked at the manuals but couldn't find any clue. I think the module should be able to generate higher frequencies but I couldn't do it. Does anyone had this issue before or what should be done?
Thanks in advance.
Best regards.
