The TCP300 and TCP400 series AC/DC current measurement systems are highly advanced solutions designed to meet today's current measurement requirements. When connected to a Tektronix oscilloscope via TEKPROBE Level II, TekConnect (using TCA-BNC) or TekVPI (using TPA-BNC) interface, current measurement and calculation becomes easy and straightforward.

Key Specifications

1Derating is related to duty cycle

Key Features

• Automatic scaling and unit determination1 - Eliminates manual calculation of amplitude and current readings on the oscilloscope screen, reducing measurement errors

• AC/DC Input Coupling

• Low insertion impedance reduces the load on the device under test

• Split core structure with simple circuit connection

• Status indicator provides notifications of visual operating status and potential fault conditions — degaussing, probe tension, overload, unterminated 50 Ω, incompatible probe type

• Reduces DC drift and noise, thereby improving low-level current measurement

• Third-party safety certification

1 Requires TDS TEKSCOPE oscilloscope or TekConnect oscilloscope with TCA-BNC adapter

Applications

• Development and analysis solutions for designers, installers and maintenance personnel in telecommunications, data communication, computer, semiconductor, power electronics and environmental protection industries:

   

   

• Power Supplies (Switching and Linear)

• Semiconductor Devices (SCR, IGBT, MOSFET, CMOS, BJT)

• Power Inverters/Converters

• Electronic Ballasts

• Industrial/Consumer Electronics

• Mobile Communications (Telephone, Satellite, Relay Stations)

• Motor Drives

• Transportation Systems (Electric Vehicles, Electric Trains, Locomotives, Avionics)

Meet Today's AC/DC Current Measurement Applications

When used with TCP312A, TCP305A or TCP303 probes, the TCPA300 amplifier delivers a full range of current measurement capabilities, filling the gap between low-current and ultra-high-current measurement products. These three probes provide current measurement for 30 A, 50 A and 150 A continuous DC current. For higher current levels, the TCPA400 amplifier with TCP404XL current probe can measure 500 A and 750 A continuous DC current, with derating dependent on duty cycle.

The TCP312A paired with TCPA300 delivers high-frequency performance, providing bandwidth of ≥100 MHz and up to 30 A DC current.

Completely Eliminate Measurement Errors and Manual Calculations

This new series of current measurement tools provides automatic control, on-screen scaling and units for users of Tektronix TDS3000, TDS500, TDS600, TDS700, TDS5000, TDS6000 and TDS7000B series oscilloscope systems (for DPO3000, MDO/MSO/DPO4000, MSO/DPO5000 and DPO7000 series oscilloscopes, a TPA-BNC adapter is required).

The TCP300/TCP400 current measurement system integrates seamlessly with TDS series oscilloscopes.

The TCPA300/400 series can also be used for current measurement even in non-TEKPROBE systems. Users only need to multiply the output voltage measured on the oscilloscope by the range setting value of the TCPA300/400 series.
