TCP300 and TCP400 Series AC/DC current measurement products are highly advanced current measurement systems that 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 - 100 MHz, 30 A DC (TCP312A)

• DC - 50 MHz, 50 A DC (TCP305A)

• DC - 15 MHz, 150 A DC (TCP303)

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

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

1 Derating is related to duty cycle

Key Features

• Automatic calibration and unit determination1 - Eliminates manual calculation, reducing measurement error for amplitude and current readings on the oscilloscope screen

• AC/DC input coupling

• Low insertion impedance reduces loading on the device under test

• Split core structure for easy circuit connection

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

• Reduces DC drift and noise to improve low-level current measurement

• 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 (Telephone, Satellite, Repeaters)

• Motor Drives

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

Meets Today's AC/DC Current Measurement Applications

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

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

Completely eliminates measurement errors and manual calculation work

This brand-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, TPA-BNC adapter is required).

The TCP300/TCP400 current measurement system can be seamlessly integrated 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 value of the TCPA300/400 series.
