Harmonic signals in AD9361

I was making a research to my engineering thesis using AD9361 and while measuring harmonics from LO in low frequencies I found that AD9361 produces a lot of spurious signals. Is it a common behaviour? In higher frequency, it looks better. 

See pictures. 

LO_freq=80 MHz

Measurment THD and harmonics power

LO_freq=2400 MHz
