Com-Power’s Current Probe and Bulk Current Injection (BCI) Probe Calibration Fixtures are each designed to accomodate the exact physical dimensions and electrical properties of the respective probe with which it is intended to be used (see cross reference table).
With the appropriate probe installed, a nominal 50 ohm transmission line impedance is maintained across the frequency range of the probe. Calibration fixtures are used for calibration of Coupling Loss/Transfer Impedance of current probes and BCI probes, as well as for the calibration of test levels for conducted immunity/susceptibility tests using BCI probes.
