LO Leakage in ADRV9361-Z7035 Board

What is the LO frequency which you are setting with ?

Also the Spectrum analyzer plot is not clear the marker frequencies are not visible can you share it again with 0dB maximum attenuation level ?

Are you running the LOL tracking Cal ?

Presently im setting LO at 150.18 MHz and im supposed to get a complete 0LO in that place.

Tx attenuation in GNU Radio sink is kept at 0dB.

Spectrum analyzer wave is even without any input there is so much amount of leakage i expect the carrier noise level to very low but in that spectrum analyzer what im seeing is a frequency at the set LO

Can you please capture the spectrum plot and share it again with the proper settings to understand better the Tx output? It is expected to achieve LO leakage is around 50 dBc as per the datasheet.

As you mentioned you are operating the chip at 150.18 MHz and are you sending any tone from the baseband?
