High noise and signal suppression

I am using AD9272-65EBZ and HSC-ADC-EVALCZ to collect ultrasound data.

I am sampling the ultrasound data, but if have high peak noise (it looks around 8kHz noise, I attached the waveform), and actual data is suppressed to very level. (I set VREF as 1V, but 500mV seems below 0.05)

I am using High_Speed_Octal_synchronous_capture.bin file to sample signal.
