signal generator demo #8

Open Adheidari opened 5 months ago

Hello, I was trying to run the signal generator example through QSFP; however, I wasn't able to get the desired output. In all tone frequencies up to 1GHz, I'm getting the same tones which are products of 153.6MHz. Although, the NCO mixer demo properly up-convert the unexpected tones via the defined carrier frequency, I'm not able to figure out where this issue is coming from.

The RF-DAC output is attached which shows the unexpected tones as I explained. image

I'll be grateful if you can help me what causes this issue.
