Product Overview

The TCP300 and TCP400 Series AC/DC current measurement family is a highly advanced current measurement system for today's current measurement needs. When connected to Tektronix oscilloscopes with TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC) interfaces, current measurements and calculations are simple and easy.

The TCPA300 amplifier, when used with TCP312A, TCP305A, or TCP303 probes, provides a wide range of current measurement capability and spans the gap between low-level milliamp measurements to very high current levels. These three probes provide current measurement capabilities of 30 A, 50 A, and 150 A DC continuous. For even higher current levels, the TCPA400 amplifier with the TCP404XL current probe measures 500 A DC continuous and 750 A DC continuous, derated with duty cycle.

Higher-frequency performance is available with the TCP312A w/TCPA300 providing ≥100 MHz bandwidth and a maximum current of 30 A DC.

Key Performance Specifications:

AC/DC measurement capabilities

DC - 100 MHz, Current Probe Amplifier (TCPA300) uses:
- DC - 100 MHz, 30 A DC (TCP312A)
- DC - 50 MHz, 50 A DC (TCP305A)
- DC - 15 MHz, 150 A DC (TCP303)
DC - 50 MHz, Current Probe Amplifier (TCPA400) Uses:
- DC - 2 MHz, 750 A DC * (TCP404XL) (500 A DC Continuous)

*Derated with duty cycle

Key Features:

Automatic scaling and units ** - Oscilloscope on-screen readout of magnitude and amps reduces measurement errors with no more hand calculations
AC/DC input coupling
Low insertion impedance reduces device under test loading
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
Low DC drift and noise allows improved low-level current measurements
3rd party safety certification

**Requires a TDS TEKSCOPE oscilloscope or a TekConnect oscilloscope with TCA-BNC adapter

Applications:

Development and analysis solutions for designers, installers, and service personnel in telecom, data comm, computer, and semiconductor power electronics environments for:
- 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)
