AIM-TTi I-prober 520 Positional Current Probe


Product Description

  • Current measurement from isolated probing of conductor
  • Dynamic range of 10mA to 20A peak to peak
  • Wide bandwidth of DC to 5MHz
  • Low noise equivalent to <6mA rms
  • Safety rated to 300V Cat II
  • Suitable for connection to any oscilloscope
  • High accuracy general purpose H-field probe
  • Convertible into 'closed magnetic circuit' current probe
  • 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

The Aim-TTi I-prober 520 is a unique current measurement device. Measurement of current normally requires it to be passed through a closed magnetic loop, typically using a 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 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.
