5MHz Positional Current Probe - 

The Aim I-prober 520 is a unique current measurement device. It can observe and measure currents in PCB tracks and other conductors where conventional current probes can’t be used. This includes captive wires into components, the legs of integrated circuits, and PCB ground planes. The I-Prober 520 uses positional H-field measurement. By placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured. The I-Prober 520 is supplied with a clip-on toroid assembly which converts it into a closed magnetic circuit probe for measuring current within a wire.
