PWM signal with 6513

[Akiel]

I have a requirement to provide 48 simultanous PWM signal, obviously I will need to vary the duty cycles, they need to be between 0v and 30v.  I believe the NI-PXI-6513 is capable of this but looking to confirm before I finalise my system

Many thanks in advance

Hi Akiel,

You can use the PXI-6513 to generate simultaneous PWM signal with varied duty cycles.  Normally, you would use a counter output for your PWM wave but because you have so many PWM waveforms, you would need to use the DIO lines.  

Please see the attached example code you could use.

Let me know if you have any questions.

Many thanks for your reply (sorry my my late one), we have had a dig into the problem and we also have a requirement a reletivly high speed, to that end we have decided to implement the PWM part of the design on a R-series (TBA) FPGA module

thanks  again tho for your time
