The TCPA300 amplifier, when used with TCP312A, TCP305A, or TCP303 probes, provides 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 TCP312A 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, MDO/MSO/DPO4000, MSO/DPO5000, and DPO7000 series oscilloscopes, the TPA-BNC adapter is required).

The TCP300/TCP400 current measurement systems seamlessly integrate with your TDS series oscilloscope.

Even non-TEKPROBE systems can use the TCPA300/400 series to make proper current measurements by simply multiplying the measured output voltage on the oscilloscope by the TCPA300/400 series range setting.
