I'm using the AD9833 to generate a varying sine wave to measure impedances, but my output is nonsensical. It's outputting a waveform with random high and low frequency components. I've checked and double checked the code I wrote to run it and it's working as intended. I have all the right timing, baud rates, bits, etc. I'm not sure what's going on and I need to get it working very soon. Could it be something with the chip itself or possible the other circuit components that have stopped working nominally? Any insights would be helpful.
Have you figured out the issue you were facing? If you have you could post here what it was and close the topic. If not, you could add more information about what you are trying to do and what you have tried. The AD9833 and AD9834 are pretty similar and have much information already on this forum.
