Hi,
I just received a second tinySA and it is failing two self-tests.? It appears to be an authentic unit.
I upgraded to V1.1-77 on both of my units.
I performed the Level Calibration and then executed Self Test.? Here are the errors:
Test 5 Above Critical

Test 7 Stopband Fail

Otherwise, ST is okay.

Did attenuator test and that seems okay.

Thank you,
Robert, WA2T
