Analysis of application characteristics and scope of TCP300/400 current measurement system

The TCP300 and TCP400 Series AC/DC current measurement series are very advanced current measurement systems that meet today's current measurement needs. Current measurements and calculations are made easy when connecting to a Tektronix oscilloscope via the TEKPROBE Level II, TekConnect (using TCA-BNC), or TekVPI (using TPA-BNC) interface.

Meets Today's AC/DC Current Measurement Applications

The TCPA300 amplifier, when used with the TCP312A, TCP305A or TCP303 probe, provides a range of current measurement capabilities, bridging the gap between low current measurement products and ultra-high current measurement products. These three probes provide current measurement capabilities for 30A, 50A, and 150A continuous DC current. For higher current levels, the TCPA400 amplifier with the TCP404XL current probe can measure continuous DC currents of 500A and 750A, with derating related to duty cycle. TCP312A with TCPA300 achieves higher frequency performance, providing ≥100MHz bandwidth and up to 30A DC current.

Comprehensive elimination of measurement errors and manual calculations

This new line of current measurement tools provides users of Tektronix TDS3000, TDS500, TDS600, TDS700, TDS5000, TDS6000 and TDS7000B Series oscilloscope systems with automated controls and on-screen scaling and units (DPO3000, MDO/MSO/DPO4000, MSO/DPO5000 and DPO7000 series oscilloscopes, requires TPA-BNC adapter). The TCP300/TCP400 current measurement system can seamlessly integrate TDS series oscilloscopes. Even non-TEKPROBE systems can use the TCPA300/400 series to perform corresponding current measurements. The user only needs to multiply the output voltage measured on the oscilloscope by the TCPA300/400 series range setting value.
