Unique technology enabling current measurement in PCB tracks with a bandwidth of DC to 5MHz, dynamic range of 10mA to 20A pk-pk. Useable with any normal oscilloscope via BNC, safety rated to 300V Cat II. Investigates waveforms in any conductor including ground planes.


More info and finance questions

The AIM-TTi I-prober 520 achieves something radically new. 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. Conventionally, current can only be measured by either breaking the circuit to insert a shunt resistor, or by surrounding the conductor by a loop of magnetic material as in a standard current probe.

The I-prober 520 enables currents, from dc up to 5MHz, to be observed and measured simply by placing its insulated tip onto the conductor.

Key Features

  • Current measurement from insulated probing of conductor
  • Suitable for observation and measurement of current in PCB tracks, component leads and ground planes
  • Wide dynamic range of 10mA to 20A peak to peak
  • Wide bandwidth of DC to 5MHz
  • Low noise figure equivalent to <6mA rms at full bandwidth
  • Safety rated to 300V Cat II (600V Cat I)
  • Suitable for connection to any oscilloscope
  • High accuracy general purpose H-field probe
  • Converts to standard ‘closed magnetic circuit’ current probe

Unique Capabilities

  • No requirement to break or surround the conductor
  • Observe and measure currents in PCB tracks directly
  • Minimal disturbance to circuit conditions through very low insertion impedance and stray capacitance
  • Useable in confined and difficult to access spaces
  • Measures current into surface mount components, IC legs and short component leads
  • Can observe currents flowing within ground planes
  • Useable on high voltage conductors and in high temperature areas
