Dear all,
I am using a PXI 7350 hardware to generate a PWM signal. The PXI is capable of generating this PWM signal by selecting parameters in the configuration VIs from the NI motion 73xx software.
There are a 14 frequencies that can be used. These are:

However, the 375.05 Hz and the ones below are exactly the same as the 48KHz and below, which results in a total of only 7 frequencies. I have tried these frequencies with the MAX software from Labview, and I am able to use the 14 frequencies from the PXI 7350 card. I have also use a PCI 7334 and I was able to use MAX and Labview to configure the PWM.
Do you think that my PXI 7350 card might be damaged?
Best wishes
