Tektronix TCPA300 current probe

Tektronix TCPA300 current probe

TCP300 and TCP400 series AC/DC current measurement series are the best current measurement systems to meet today's current measurement needs. When TEKPROBE Level II, TekConnect (using TCA-BNC) or TekVPI (using TPA-BNC) interfaces are connected to TekProbe oscilloscopes, current measurements and calculations are easy and simple.

Main performance index

AC/DC measurement function

DC-100 MHz, Current Probe Amplifier (TCPA300) uses:

Dc-100 MHz, 30 A DC (TCP312A)

Dc-50 MHz, 50 A DC (TCP305A)

Dc-15 MHz, 150 A DC (TCP303)

DC-50 MHz, Current Probe Amplifier (TCPA400) uses:

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

1 The derating is related to duty cycle

Main feature

Automatic calibration and determination of the amplitude and current reading of the unit 1 - oscilloscope screen reduces measurement errors by eliminating manual calculations

AC/DC input coupling

Low insertion impedance reduces the load on the device under test

Split core structure, simple circuit connection

The status indicator provides notification of virtual operating status and potential error conditions - demagnetization, probe length, overload, misconnection 50 incompatible probe types

Dc drift and noise are reduced for improved low-level current measurement

Third-party security certification

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

Development and analytical solutions for designers, installers and maintainers in the telecommunications, data communications, computer and semiconductor power electronics environmental protection industries:

Power supply (switching and linear)

Semiconductor devices (SCR, IGBT, MOSFET, CMOS, BJT)

Power inverter/converter

Electronic ballast

Industrial/consumer electronics

Mobile communications (telephone, satellite, relay station)

Motor driver

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 range of current measurement capabilities that bridge the gap between low-current measurement products and ultra-high current measurement products. These three probes provide current measurement for 30 A, 50 A, and 150 A continuous DC currents. For higher current levels, the TCPA400 amplifier with the TCP404XL current probe can measure continuous DC currents at 500A and 750A, with derating related to duty cycle.

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

Total elimination of measurement errors and manual calculation work

The new series of current measuring tools are Tektronix TDS3000, TDS500, TDS600, TDS700, TDS5000, TDS6000 and TDS7000B Users of the series oscilloscope system are provided with automatic control functions and screen scales and units (DPO3000, MDO/MSO/DPO4000, MSO/DPO5000 and DPO7000 series oscilloscopes require a TPA-BNC adapter).

The TCP300/TCP400 current measurement system can be seamlessly integrated with the TDS series oscilloscope.

Even the non-TekProbe system can also use the TCPA300/400 series to perform the corresponding current measurement, the user only needs to multiply the output voltage measured on the oscilloscope by the TCPA300/400 series range setting value.
