AD9361 ADC spectrum problem

I am using AD9361 and i tuned AD9361 to 341 MHz, i feed 342 MHz tone from signal generator Such way that i will receive 1 MHz tone to ADC. This ADC data i captured from Chip scope analyzer and plotted by using Matlab.


In Plotted spectrum i observed some spurious offset of 178 KHz from main signal, these signals are dominating spectrum and i couldn't able to eliminate these spurious. Please help me to suppress these.


Here i attached the Matlab spectrum images. One image with wider bandwidth and another one is lesser bandwidth


Thanks for support
