Bulk Current Injection (BCI) Tests and Fiber-Optics

Michigan Scientific Corporation (MSC) Fiber-Optic Systems are known for the superior stability that is necessary for monitoring equipment applications, especially when preforming Bulk Current Injection (BCI) testing. By accurately transmitting electrical signals over fiber-optic cables from sources in high electromagnetic field environments, the electromagnetic interference (EMI) and the radio frequency interference (RFI) do not corrupt the measurements that are obtained from these tests, and can accurately determine the electromagnetic compatibility (EMC) of vehicle components. With BCI tests being performed on vehicles within the automotive, agricultural, aerospace, and military industries, it is important that reliable and accurate equipment is used. 

FO-HBAVT_HBAVRMSC Fiber-Optic Systems are commonly used for BCI tests, as they are ideal for seeking EMC laboratory certification and are EMI/RFI hardened for both immunity and emissions. They also monitor or source signals for component and system level EMC testing with superior signal stability. This stability is crucial for measurements taken during harsh EMC testing. 

Bulk Current Injection (BCI) Tests 

BCI testing is a crucial part of testing the immunity of communication line wiring harnesses. By confirming radio frequency signals (which have a range of 10 kHz to 200 MHz) of a power supply line, it is possible to determine if RFI or EMI signals will cause degradation of performance to the equipment under test. This allows engineers to use this data to mitigate any harmful interference that comes from external electromagnetic energy sources, allowing consumers to safely operate vehicles without outside energy sources impacting the vehicle electronics.
