DAC is used for generating sinus wave 1kHz.
1000 sample is over DMA transferred on DAC 1MHz/1000SPS = 1kHz
It would be good to start each sinusoid nullify one of the counters.
This signal, after passing through something DUT return on ADC
After generated fifty sinus wave is started ADC and over DMA make 1000 measure on 1MHz
What is the purpose?
Determine the attenuation and shift waves at DUT.
