A.H. Systems Inc. Broadband Current Probe Model BCP-620

The BCP-620 broadband current probe is a toroidal transformer used to measure RF current without directly connecting to the electrical conductor or cable under test. The conductor passing through the aperature of the current probe acts as a single turn primary of the transformer. The secondary is designed for a 50 ohm system such as an EMI meter or spectrum analyzer. This current probe can handle 60 amperes of pulse currents and 40 amperes of CW between the usable frequency range of 10 KHz to 500 MHz.
