Tektronix TCP303 Current Probe

Overview

The Tektronix TCP303 is an AC/DC current probe designed for high-current measurement applications up to 150 A DC. Part of the TCP300 series, it provides precise current measurements when connected to compatible Tektronix oscilloscopes via TEKPROBE Level II, TekConnect (with TCA-BNC), or TekVPI (with TPA-BNC) interfaces. The probe features split-core construction for non-invasive circuit connection and works with the TCPA300 current probe amplifier for automatic scaling and on-screen readout.

Key Features

• DC to 15 MHz bandwidth with 150 A DC measurement capability
• AC/DC input coupling for flexible current measurement
• Split-core construction for easy circuit connection without component removal
• Automatic scaling and unit display on compatible oscilloscopes
• Low insertion impedance reduces loading on device under test
• Status indicators show operating status and error conditions (degauss, probe open, overload, impedance mismatch, incompatible probe type)
• Low DC drift and noise for improved low-level current measurements
• Third-party safety certification

Applications

• Power supply analysis (switching and linear designs)
• Semiconductor device testing (SCRs, IGBTs, MOSFETs, CMOS, BJTs)
• Power inverter and converter development
• Electronic ballast design and troubleshooting
• Industrial and consumer electronics development
• Mobile communications infrastructure (phones, satellites, relay stations)
• Motor drive and transportation systems (electric vehicles, trains, locomotives, avionics)
