TekBox TBBCI1-800K420 Bulk Current Injection Probe

Overview

The TekBox TBBCI1-800K420 is a snap-on Bulk Current Injection (BCI) probe designed for automotive EMC testing and conducted immunity assessment. Engineered to ISO 11452-4 and IEC/EN 61000-4-6 standards, it enables evaluation of automotive product immunity to conducted RF disturbances in the frequency range of 1 MHz to 400 MHz, with characterized operation extending to 10 kHz–500 MHz. The probe supports severity levels I through IV and custom severity level V for comprehensive automotive compliance testing.
