TCP303 Tektronix Current Probe



  • AC / DC Measurement Capabilities: DC – 15 MHz, 150 A DC (Requires TCPA300 amplifier)
  • Automatic Scaling and Units– Oscilloscope On-Screen Readout of Magnitude and Units Reduces Measurement Errors with No More Hand Calculations
  • AC / DC Input Coupling
  • Low Insertion Impedance Reduces Device Under Test Loading
  • Small Mechanical Package – Less Desktop Space, Easier Storage and Handling
  • Split-Core Construction Allows Easy Circuit Connection
  • Status indicators provide visual operating status and notification of potential error conditions - degauss, probe open, overload, not terminated into 50 Ω, noncompatible probe type
  • Lower DC Drift and Noise Allows Improved Low Level Current Measurements
  • Certified for use in U.S., Canada, and Europe. Complies with applicable IEC standards


  • Power Supplies (Switching and Linear)
  • Semiconductor Devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs)
  • Power Inverters/Converters
  • Electronic Ballasts
  • Industrial /Consumer Electronics
  • Mobile Communications (Phone, Satellite, Relay Stations)
  • Motor Drives
  • Transportation Systems (Electronic Vehicles, Electric Trains, Locomotives, Avionics)


  • 15 MHz
  • 150 A

The Tektronix TCP303 AC/DC Current Measurement family is a highly advanced current measurement system for today's current measurement needs. 

The split-core probes incorporate both transformer and Hall effect technology to provide broad bandwidth measurement capabilities from DC up to 100 MHz at current levels as low as 1 milliamp to thousands of amps (when used with CT4 current transformer). 

When connected to Tektronix TDS Oscilloscopes with TEKPROBE Level II or TekConnect (w/TCA-BNC) interfaces, current measurements and calculations are simple and easy. Additional measurement power is available with add on software such as the TDSPWR2 power measurements package.
