Worked Example

Verified calculation

Given:

  • Measured Conducted Emission (Quasi-Peak) = 42.5
  • CISPR 32 Class B Limit (Quasi-Peak) = 46

Expected Result:

  • Emission Margin = 3.5

Engineering Interpretation:

Under the given input conditions, the calculated result is: Emission Margin = 3.5 dB.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
