Noise and wrong peek to peek in sign wave generated by ADuCM350

Category: Hardware
Product Number: ADuCM350
Software Version: ImpedanceMeasurement_2Wire - Revision: 29403


I am evaluating Impedance measurement example for ADuCM350 in 2-wire configuration. But the waveform I am observing in DSO is noisy and peek to peak is wrong. But I am correct frequency that I have set in firmware(I have changed the frequency from 10KHz in example to 1KHz) . I have attached the image if waveform I am getting in AFE daughter board. Please look into the issue
