Hi,
Can you provide a scope plot of PXIE-6570 running at 100MHz(50% Duty Cycle)?
We tried running our PXIE-6570 at 100MHz on our NI_GP2 platform with the single board interface(SBI) on it, with the DUT unconnected. Though we were able to see a 100MHz signal, integrity of the rise and fall edge is not that good. Signal looks more of a sine wave.
regards,
Tommy
