The Tekbox TBBCI1-800K420 is a bulk current injection probe characterized in the frequency range of 10 kHz to 500 MHz. The CBI probe is designed for immunity testing of automotive products according to ISO 11452-4 and IEC/ EN 61000-4-6 standards (1 MHz — 400 MHz), and in the frequency range 250 kHz — 230 MHz it is compliant with their insertion loss specifications. The insertion loss of the probe is 5 dB for most of its bandwidth, and it is possible to inject severity levels I (60 mA), II (100 mA), III (150 mA), IV (200 mA) and customer specific severity level V up to 350 mA. At last, the TBBCI1-800K420 can also be used for monitoring purposes.
We also sell the calibrator fixture for the TBBCI1-800K420 probe, the TBBCI1-CAL.
Model overview
Currently we have two Tekbox models in our catalogue, which differ in terms of their frequency range and thus their compliant standards.
