The TBCP2-750 from Tekbox is a snap-on RF current monitoring probe designed for EMC pre-compliance testing. The probe is characterised over the frequency range from 30kHz to 750MHz, with a standard flat frequency response across this range. It has a typical transfer impedance of 0dBΩ. The TBCP2-750 can handle currents up to 400A from DC to 400Hz without affecting transfer impedance. Because the TBCP2 is a snap-on probe, it can be easily attached to cables with large plugs on the ends.
We also sell the calibrator for the TBCP2, see this page.
