PWM using USB 6251

[Sriniketh]

I am new to labview, I would like to generate PWM signals of On time in the order of 0.1µs with duty cycle of 1%. I have seen sample programs for generating a PWM signal . I have NI USB 6251 hardware, Is it possible to generate the PWM of the mentioned requirement. I need this PWM signal to switch IGBT drivers.

If this cannot be used, kindly suggest me what hardware to be used _

Thanks in advance

Hi Sriniketh,

your NI6251 provides two counters, use them to generate your PWM signal!

Open the example finder and look for PWM generation example VIs to get you started…

Thank you Gerd

Can I Use two counters separately for different pwm ?.

Also suggest me about the hardwares. I have USB 6251, In addition to this what would i need ?

Hi Sriniketh,

why don't you call your local NI office? They will be happy to help you selct your DAQ hardware!

Each counter can be used to generate a PWM signal: two counters, two PWM signals…
