Hi All,

Currently we are working on a Project which is related to Telecommunication. Guide us how to configure the Registers of AD9361. We are currently using Gnu radio 3.8, by setting the LO  Frequency and other required settings for our application. Where as it is observed that there is a LO Frequency Leakage from the Tx of AD9361.

In addition to the images captured in CRO, two more images captured on Spectrum analyser are added up for your review and comments.

PFA Images attached for reference.

RF Frequency=960 MHz & Level=-10dBm

RF Frequency=960 MHz & Level=-20dBm

The peak in spectrum analyser is just after GNU Blocks are made to run. Even without any RF input signal, Lo leakage is observed at the output.

Kindly Provide a info/solution to resolve this issue



Added product number, category, and software version.

  • LO leakage is expected and amplitude will be lower, if you observed higher LO leakage and Image, run the Rx OEC and DC offset calibrations.

    The peak in spectrum analyser is just after GNU Blocks are made to run. Even without any RF input signal, Lo leakage is observed at the output.

    Can you share the spectrum image with the proper markers placed for all signals in the spectrum?
