A Bulk Current Injection Probe (BCIP) is a vital piece of equipment needed to perform cable bundle conducted susceptibility testing. Bulk current injection testing is just one more way to test electrical equipment for electromagnetic compatibility (EMC).
In these tests, the BCIP injects a transient signal or radio frequency (RF) current into cables that are connected to the equipment under test (EUT). With these electrical phenomena introduced to the EUT system, we can assess whether the equipment is susceptible to conducted electromagnetic energy.
The primary purpose of using a BCIP is for testing cable bundles and the equipment interconnected for electromagnetic compatibility. With this device being able to clamp-on, there is an ease of use for certain applications that will require this equipment. The BCIP not only offers easy access for EMC testing but offers a wide range of sizes to fit a variety of circuits and cables.
There are many different tools to conduct EMC testing, including a coupling-decoupling network
(CDN). A coupling-decoupling network is primarily used for commercial and automotive testing, while a bulk current injection probe meets many standards that test for radio frequency. The BCIP does perform RF sweep testing to meet commercial standards like IEC 61000-4-6
, it also tests for many of these military and aeronautics standards:
