Current Probes for EMC TestingPearson Clamp-on Current and Injection Probes are used to make accurate AC current measurements to meet many of the EMC standards. EMI, surge, lightning, and other complex current wave-shapes can also be viewed with a Pearson Current Probe. A typical model has a flat midband response with a 3 dB bandwidth of 6 Hz to 15 MHz. Current as low as 10 micro amps (20 dBuA) and frequencies as high as 400 MHz can be viewed with a Pearson Clamp-on Current Probe.

Below are some of the EMC standards and the recommended Pearson Current Probe, along with its transfer impedance curve, to assist with those measurements.
