The BCP-620 RF 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 aperture 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.

Transfer impedance is defined as the ratio of the voltage developed across 50 ohms divided by the current flowing in the primary winding. Since EMI meters are selective, RF volt meters reading directly in RF volts, current conversion is simplified using Ohms law. The transfer impedance of the current probe is divided into the voltage measured at the output of the probe to obtain current in the conductor or cable under test. In dB, the current (dBuA) is equal to the reciever reading (in dBuV) - the transfer impedance (dBΩ).

Features:

  • 10 KHz to 500 MHz
  • Ideal for BCI testing; ISO 11452-4, MIL-STD-461 CS114
  • High Current Capability
  • Individually Calibrated
  • Frequency Range: 10 KHz - 500 MHz
  • Transfer Impedance (dBohm): -29 to 17
  • Max Primary Current (DC - 60 Hz): 200 Amps
  • Max Primary Current(400 Hz): 200 Amps
  • Max Primary Current CW:40 Amps
  • Peak Pulse Current: 60 Amps
  • Connector: N-Type, Female
