Increased performance and simplicity

The TCP300 and TCP400 series AC/DC Current Measurement family is a highly advanced current measurement system for today's current measurement needs. The split-core probes incorporate both transformer and Hall-effect technology to provide broad bandwidth measurement capabilities from DC up to 100 MHz at current levels as low as 1 milliamp to thousands of amps (when used with CT4 current transformer). When connected to Tektronix Oscilloscopes with TEKPROBE Level II, TekConnect (w/ TCA-BNC) or TekVPI (w/ TPA-BNC) interfaces, current measurements and calculations are simple and easy.

Additional measurement power is available with add-on software such as the TDSPWR2 power measurements package. With all this measurement power, current measurements have never been easier.

*1 Derated with Duty Cycle

*2 Requires a TDS TEKPROBE Oscilloscope or a TekConnect Oscilloscope with TCA-BNC

Meets today's AC/DC current measurement applications

The TCPA300 amplifier, when used with TCP312, TCP305, or TCP303 probes, provide a wide range of current measurement capability and spans the gap between low-level milliamp measurements to very high current levels. These three probes provide current measurement capabilities of 30 A, 50 A, and 150 A DC continuous. For even higher current levels, the TCPA400 amplifier with the TCP404XL current probe measures 500 A DC continuous and 750 A DC continuous, derated with duty cycle.

Higher frequency performance is available with the TCP312 w/TCPA300 providing ≥100-MHz bandwidth and a maximum current of 30 A DC.

Measurement errors and manual calculations are now a thing of the past

With this new series of current measurement tools, automatic control and on-screen scaling and units is provided for users of Tektronix TDS3000, TDS500, TDS600, TDS700, TDS5000, TDS6000, and TDS7000B series oscilloscope systems (the DPO3000, DPO4000, and DPO7000 series oscilloscopes, the TPA-BNC adapter is required).

The TCP300/TCP400 Current Measurement Systems seamlessly integrate with your TDS series oscilloscope and the TDSPWR2 software package to easily make those time-consuming power measurements and calculations for you.

Even non-TEKPROBE systems can use the TCPA 300/400 series to make proper current measurements by simply multiplying the measured output voltage on the oscilloscope by the TCPA 300/400 series range setting.
