Hi, there

I have a board STM32F407 and i want to cretate a wave form so if i will plug the output into spectrum analizer

i will get 10MHz 30Mhz 100Mhz harmonics displayed on. Is it possible to do?

One idea that i thought is to try and create such time signal in MATLAB(which FFT has such properties).

So i will have in matlab some mathematical time domain samples of the signal,

and then try and transform the samples into DAC digital values.

However, its very tough because the samples will be very close to each other. I am not sure the DAC could respond so fast.

Is there anyone give me some ideas? Many thanks.
