Re: "CALIBRATE above 5.34GHz" throws a "Signal level too low or not on frequency" error #bug_report


 

Thanks Erik

I assume that leveloffset harmonic is accessible from the console commands?

There is already a default value set to minimize the step when transitioning to harmonic mode but due to manufacturing tolerances this step is not equal for all tinySA Ultra.
The uncertainty is expected to be below +/- 5dB If you have done a normal level calibration and you have a calibrated or known source above 5.34 GHz you can manually do the calibration by measuring the know source and changing the value of leveloffset harmonic until the measured value is equal to the known output power of the source.
