Hello Babmi,
Can you elaborate more on what/how you plan to do? Are you using a LabVIEW Real-Time system? If so, which hardware and software do you have? If you have already developed a Real-Time VI and need help with that, please take a screenshot and post it so everyone can better understand your issue.
Just to clarify: Real-Time operating systems are deterministic, not instant. They allow the timed execution of a loop within a finite amount of time and minimal jitter. What acquisition rate are you looking for? What kind of data are you performing a FFT on?
Please post back with more specific details about your system, and exactly what you would like to do. Thanks
🙂
