TMS320F28379d DAC 100kHz

Hello,

I am reading an analog signal at 100kHz. I use the solver step size: 1e-6 and got the waveform as below. However, I cannot reduce my step size. For example, if I enter 1e-7, there is no waveform any more on my oscilloscope. May I ask for some help to get a nice 100kHz waveform? I contacted the TI support already and they said based on the ADC clock, I supposed to get more samples.

Thank you,

Hi, did you solve your problem? I have a similar problem, I want to generate a 30 kHz sinusoidal wave using the DAC, but when I increase the sample time it doesn't work.
