LimeSDR Mini LimeQuickTest Fails

The LimeQuickTest fails with my LimeSDR Mini when connected via USB3.0 with no antennas or cables attached to the SMAs. Based upon other posts on the forum, it appears that this device has a hardware defect.

Can a banner be added to the LimeQuickTest application warning people that the results are only valid if the board is cold with no antennas connected.

Hello, I performed the test cold with no antennas attached. I believe that there could be a hardware issue and the support email correspondent told me to verify with the staff on the forum.

Good idea. @garmus, what do you think?

Thanks for posting the results. @zack, anything else to suggest or do we need to arrange an RMA?

Hi @mzs,

Done already, just not published yet :slight_smile:
