Bulk Current Injection (BCI) Probes

Bulk current injection probes are used to inductively couple large RF currents into conductors passing through. They come in two different styles, a clamping style that can be used for hard to access cable bundles and a window style to pass wires and cables through. Signal, control, and power circuits of EUT (equipment under test) are the conductors when testing for conducted immunity. Bulk current injection probes operate as a single turn primary, multiple turn secondary transformer, by placing low series impedance in the probed power line while pushing a functional signal to a 50ohm receiver. The ratio of output voltage into a standard load divided by the net current moving through the probe equals the current probe's transfer impedance. MIL-STD-461IEC 61000-4-6, and ISO 11452-4 commonly require the injection of low-level RF signals and high-frequency current into wires and cable bundles, making a current injection probe an essential item to adhere to testing requirements.

Avalon Test Equipment carries a variety of bulk current injection probes from top manufacturers (Com-PowerA.H. Systems, and more) to meet your testing requirements. Rent from Avalon and Test With Confidence®.
