I want to getting a voltage level from AD9236. But when I test AD9236 (ADC) It is difficult to anlayze a signal with low frequency. As this reason, I can't get a DC(direct current) voltage value.
ADC is always used for fluctuating signal?
As far as I know, ADC is convert analog level to digital data.
(Left one is squre wave sampled result. The other is sine wave sampled result)
squre wave, sine wave source is wave generator.
Below picture is the oscilloscope from generator. I think generator is not wrong.
Yes... My Board circuit is configured with single ended... this includes capacitor..it is reason that I can not analyze low-frequency.. Thank you so much. I will learn more
