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-461, IEC 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.

Part of the test equipment required by most of the Bulk Current Injection test procedure specifications. Allows the user the quickly and easily calibrate the injection probe prior to performing compliance testing.
Injection Probe calibration fixtures are a part of the test equipment required by most of the Bulk Current Injection Test Procedure Specifications. This test fixture allows the user to quickly and easily calibrate the injection probe prior to performing the compliance testing.
Designed for the IEC 61000-4-6 Ed 4.0, section 188.8.131.52 – 184.108.40.206 that states “…the increase of the transmission loss of the test jig, produced by the insertion of the Current Clamp, shall not exceed 1.6 dB”. This 1.6 dB requirement is verified by subtracting the insertion loss of the calibration fixture without the Clamp in place from the fixture insertion loss with the Clamp in place.
