TCP300 and TCP400 series AC/DC current measurement is an advanced current measurement system that meets today's current measurement demands. When connected to a Tektronix oscilloscope via TEKPROBE Level II, TekConnect (using TCA-BNC) or TekVPI (using TPA-BNC) interfaces, current measurement and calculation becomes easy and straightforward.

Key Specifications

AC/DC Measurement Capability

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

• DC - 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 the oscilloscope screen eliminate manual calculation, reducing measurement errors

• AC/DC Input Coupling

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

• Split core structure enables easy circuit connection

• Status indicators provide notification of real-time operating status and potential error conditions — degaussing, probe tension, overload, 50 Ω unterminated, incompatible probe type

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

• Third-party safety certification

1Requires 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)

Meeting 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 support current measurement of 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.

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

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

TCP300/TCP400 current measurement systems 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.
