Observe and measure current in a PCB track

I-prober with scope
  • Make measurements via non-contact probing
  • Suitable for observation and measurement of current in component leads & ground planes as well as PCB tracks
  • Wide dynamic range of 10mA to 20A pk to pk
  • Wide bandwidth of DC to 5MHz
  • Low noise equivalent to <6mA rms at full bandwidth
  • Minimal disturbance to circuit conditions through very low insertion impedance and stray capacitance
  • Safety rated to 300V Cat II (600V Cat I)
  • Suitable for connection to any oscilloscope
  • High accuracy general purpose H-field probe
  • Convertible into "closed magnetic circuit" current probe

The Aim I-prober 520

The Aim I-prober 520 positional current probe is unlike any other current measurement device available.

Calibrated measurement of current normally requires the current to be passed through a closed magnetic loop. Typically this is done using some form of split clamp device. Whereas this is suitable for individual wires, it is of no use for measuring current in PCB tracks.

The I-prober 520 is a compact hand-held probe which is used with an oscilloscope. By placing the insulated tip of the probe onto a PCB track, the current flowing in the track can be observed and measured.

How does it work?

Learn about the technical problems of current measurement in PCB tracks. This is a challenge that probe designers have battled with over the years without success - until now. Aim-TTi have used patented technology to enable currents to be observed and measured by precise positional measurement of field.
