Complies with applicable IEC standards Applications: Development and Analysis for: Power Supplies, Semiconductor Devices, Power Inverters/Converters, Electronic Ballasts, Industrial/Consumer Electronics, Mobile Communications, Motor Drives, Transportation Systems The TCP305 AC/DC current measurement is a highly advanced current measurement system for today's current measurement needs. 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. 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 30A, 50A, and 150A DC continuous. For even higher current levels, the TCPA400 amplifier with the TCP404XL current probe measures 500A DC continuous and 750A 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 30A DC. With this new series of current measurement tools, automatic control and on- screen scaling and units is provided for users of Tektronix TDS3000, TDS400A, TDS500, TDS600, TDS700, TDS5000, TDS6000 and TDS7000 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.
