Abstract :
We report on an experiment (the calibration of a wideband inductive current probe) where widely different calibration methods are applied to the same unit under test depending on the frequency being tested in order measure inside the “LF-RF gap”. The sought outcome is the convergence of results obtained between the LF side (100 Hz to 60 kHz) and the HF side (10 kHz to 20 MHz).
