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

Key Specifications

AC/DC Measurement Capability

• DC to 100 MHz, for use with current probe amplifier (TCPA300):

• DC to 100 MHz, 30 A DC (TCP312A)

• DC to 50 MHz, 50 A DC (TCP305A)

• DC to 15 MHz, 150 A DC (TCP303)

• DC to 50 MHz, for use with current probe amplifier (TCPA400):

• DC to 2 MHz, 750 A DC 1 (TCP404XL) (500 A DC continuous current)

1Derating is related to duty cycle

Key Features

• Automatic scaling and unit determination1 - Amplitude and current readings on oscilloscope screen reduce measurement error by eliminating manual calculation

• AC/DC Input Coupling

• Low insertion impedance reduces loading on the device under test

• Split core structure enables easy circuit connection

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

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

• Third-party safety certification

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

Applications

• Development and analysis solutions for designers, installers and maintenance technicians in telecommunications, data communications, 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, repeater stations)

• Motor Drives

• Transportation Systems (electric vehicles, electric trains, locomotives, avionics)

Meets the Requirements of Today's AC/DC Current Measurement Applications

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

When used with TCPA300, the TCP312A delivers higher-frequency performance, offering a bandwidth of ≥100 MHz and a maximum DC current of up to 30A.

Completely Eliminates Measurement Error and Manual Calculation

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 (TPA-BNC adapter is required for DPO3000, MDO/MSO/DPO4000, MSO/DPO5000 and DPO7000 series oscilloscopes).

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

Even for non-TEKPROBE systems, the TCPA300/400 series can be used to perform corresponding current measurements, and users only need to multiply the output voltage measured on the oscilloscope by the range setting value of the TCPA300/400 series.
