I just did the self-test and the attenuator test failed.

I have almost always had a 30 dB pad on the input when looking at broadband or unknown levels.? I’m an RF engineer and I think I know what I’m doing.? Or at least I did.

I did not do any firmware upgrades, and the version is: tinySA_v1.3-111gcb2fe54 dated May 15, 2021.

This is not a clone.

I only have one hand, so I can’t repair it.? Who can?

?

Kind Regards,

Dave
