RadiMation Error: 536871966
There is no average probe selected
This error happens when you are doing a Radiated Immunity calibration and do not have at least one averaging probe selected. For a RI calibration at least one averaging probe is mandatory to do the calibration.
Solution
Re-open your Radiated Immunity calibration test file and go to 'Field Probes' and make sure that at least one of the probes has the averaging checkbox checked.
