Harmonics of the RF output
Hi,
First of all, thank you so much for sharing your source code. It help me lot on building my codes. I have successfully driven the board to generat desired frequency and performing sweep. However, I did find some anoying phenomones on the RF output. I monitored the output with a spectrum analyzer, I notice there are multiple harmonic peaks on the spectrum. I have no idea why this appeared. I tried out with the colne board from eBay and a official board from ADI. Both of them have the same issue. Do you have the same issue when you generate the frequency with your board? Do you know how to mitigate those harmonics? Really appreciare for you help!
Thanks,
Shinong
