I am working on design which consist of XADC using Microblaze , sampling on 1Msps, via channel 4 , I am getting samples through Ethernet but when I am plotting it or takING FFT of it ( using online FFT calculator) . I am getting pulse like this which is not good , and also I am worried about my samples values, which are coming over 4096 (maximum range of 12 bit ADC).
input frequency 100KHz sine wave.
I am attaching picture of samples and waveform. please review it and give me some suggestion.
