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

1Derating is related to duty cycle

Key Features

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

• AC/DC input coupling

• Low insertion impedance reduces loading on the device under test

• Split core structure for simple circuit connection

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

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

• Third-party safety certification

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

Applications

• Development and analysis solutions for designers, installers and maintenance personnel 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 (telephones, satellites, repeaters)

• 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 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 support continuous DC current measurement of 30 A, 50 A and 150 A. For higher current levels, the TCPA400 amplifier paired with a TCP404XL current probe can measure 500A and 750A continuous DC current, with derating dependent on duty cycle.

TCP312A with TCPA300 delivers higher frequency performance, providing a bandwidth of ≥100 MHz and DC current up to 30A.

Completely eliminates 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 seamlessly integrates with TDS series oscilloscopes.

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