PWM measurement - NI USB DAQ 6259 setup

[prabubharathi]

Hi all,

I am new to DAQ application.

I want to measure the PWM output which comes out from my board using the NI USB DAQ 6259. I want to understand the how I have to wire PWM output of my board to DAQ card.

Here my application is to control the 24V motor.

Regards,

Hi,

1. Make sure that your PWM is within the voltage limit of the DAQ.

2. What exactly do you want to measure from the PWM?  Do you just want to display it on the screen, calculate duty cycle, or what?
