Introduction

The BCM 0220M Surface Current Probe is used for measuring induced currents on conductor surfaces under electromagnetic radiation environments. This product transmits surface‑induced currents to recording equipment in the form of voltage via electromagnetic coupling. It features undistorted waveforms and physical isolation from current‑carrying conductors.

BCM 0220M broadband current monitoring clamp s21 curve

Explanation:

When the load impedance is 50 Ω, the transfer impedance (dB) is s21+34dB+25dB;

When the load impedance is 1M Ω: transfer impedance (dB) = s21+34dB+6dB+25dB.

Specification

Technical Parameters

* When the broadband current monitoring clamp is terminated at 50 Ω, the sensitivity (transfer impedance) is 0.005V/A;

** When measuring surface current, dividing the measured current value by the effective length of the probe is the surface current density, measured in A/m.
