Tektronix TCP312A Current Probe

Overview

The Tektronix TCP312A is an advanced AC/DC current measurement probe designed for integration with Tektronix oscilloscopes equipped with TEKPROBE Level II, TekConnect, or TekVPI interfaces. It provides seamless current measurement with automatic scaling and on-screen readout, eliminating the need for manual calculations and reducing measurement errors.

Key Features

• AC/DC measurement capabilities: DC to 100 MHz bandwidth
• Maximum current: 30 A DC
• Automatic scaling and units display on oscilloscope screen
• AC/DC input coupling for flexible measurements
• Low insertion impedance reduces device under test loading
• Split-core construction allows easy circuit connection without circuit interruption
• Status indicators for operating status and error conditions (degauss, probe open, overload, terminated impedance, compatibility)
• Low DC drift and noise for improved low-level current measurements
• Third-party safety certification

Applications

• Power supplies (switching and linear)
• Semiconductor devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs)
• Power inverters and converters
• Electronic ballasts
• Industrial and consumer electronics
• Mobile communications (phones, satellite, relay stations)
• Motor drives
• Transportation systems (electric vehicles, trains, locomotives, avionics)

Included Accessories

• TCPA300 Current Probe Amplifier (required for use)
• Oscilloscope interface adapter (TekConnect, TPA-BNC, or TEKPROBE compatible)
