Hi everyone,
I am currently trying to generate a PWM signal on the NI 9683 board. However, I am constantly getting a constant output (shown in attachment) and not a PWM signal. My modulation index is 0.5 and the code I am using is attached too. I am using LabVIEW version 13.
Also, I have read that the accumulator increment in the DDS is done by (desired waveform freq X 2^32)/ (freq of update loop). Hence my question is if the update loop is the HSDO Perios(Ticks) inside the flat sequence?
Thanks for any assistance.
