Current Probe

Tektronix current probe solutions offer:

  • The broadest range of AC/DC and AC-only current probes
  • Measurement accuracy from uAs to 2000 A
  • Best-in-class bandwidth up to 120 MHz
  • Best-in-class current clamp sensitivity down to 1 mA
  • The only products with 3rd Party Safety Certification (UL, CSA, ETL)
  • The only products with bare wire voltage ratings
  • Automatic readout and scaling when used with Tektronix oscilloscopes so you don’t have to convert volts to amps or manually set the scaling
