I am working on AD9361 and i am facing some spurious issues in Transmitter output. I tuned transmitter in to 221 MHz and in spectrum i am seeing 221 MHz and along with +/- 4 MHz offset away some frequency products, which are 26 dBc away from main signal. I tuned LO to 220 MHZ and i generated 1 MHz from DAC.
Please help to suppress those spurious and i observed some other spurious spurious, they are below 60 dBc and over all i can say spectrum is not clear.
Please help me about this.
