Bulk Current Injection Probes

Bulk Current Injection Probes are used to inject RF-current into cables of electrical equipment to test the susceptibility against radiated electromagnetic energy. Tekbox BCI-probes can be clamped around wire bundles with up to 27 mm. They are designed to meet the specifcations of the standards IC 61000-4-6 (domestic and industrial products) and ISO 11452-4 (automotive products).

Tekbox supplies suitable wideband power amplifiers to drive the BCI probes:

TBMDA-CDN25 for immunity tests according to IC 61000-4-6
TBMDA-BCI25 for immunity tests according to ISO 11452-4

The calibration fixture TBBCI1-CAL is suitable for both BCI-probe models
