Offset parameter in SBRIO9606 with RMC 9683

I am in new in LABVIEW. I am using NI9683 with SBRIO( NI 9606) for inverter control. I am giving the voltage and current sensor outputs to the simultaneous analog inputs pins of the NI9683. I am giving a sinusoidal periodic signals to the simultaneous analog pins in FPGA platform.These signals are seen in oscilloscope as sinusoidal. However,in LABVIEW graphical platform these signal are coming as distorted. Please advise how to get same input signal in the graphical platform of the LABVIEW.

Re: Offset parameter in SBRIO9606 with RMC 9683

Hi,

 

In what way are the measured signals distorted? Could it be aliasing from not sampling fast enough? If that's the case, how fast is your acquisition loop in your FPGA VI and what is the frequency of the signal?

 

Overall, could you describe how the signal is different than expected and how you're acquiring it in software?

 

If you think it's an issue with your LabVIEW code it would be helpful to see some screenshots. Maybe there's something wrong in the FPGA VI or LabVIEW project.
