TBBCI1-200K280 snap-on bulk current injection probe

The TBBCI1-200K280 is a snap-on Bulk Current Injection probe, expanding the Tekbox product range of affordable EMC pre-compliance test equipment.

The BCI probe has been designed primarily for conducted immunity testing in the frequency range 150 kHz to 230 MHz, according to standard IEC / EN 61000-4-6. The insertion loss is 8 dB for most of its bandwidth and it is fully compliant with the insertion loss specification of  IEC / EN 61000-4-6. The probe is individually characterized and usable in the frequency range 10 kHz – 300 MHz. It can inject severity levels 1, 2, 3 and level X up to 30V into a conducted immunity test set-up according to IEC/EN 61000-4-6.

The probe can also be used for RF current monitoring applications.

The aperture of the RF current monitoring probe is 27 mm. The typical insertion loss is 8 dB and the typical transfer impedance is 26 dB Ohm.
