AC/DC Current Probe; Instruction Sheet; Probe Cover; Certificate of Traceable Calibration

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 TDS Oscilloscopes with TEKPROBE Level II or TekConnect (w/TCA-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.

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. Status LEDs quickly show you TCP300/400 series operating status or potential error conditions that may have caused measurement errors in the past.

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.
