AC/DC Current Measurement Systems TCPA300, TCP312A, TCP305A, TCP303, TCPA400, TCP404XL Datasheet Low DC drift and noise allows improved low-level current measurements 3rd party safety certification Applications Development and analysis solutions for designers, installers, and service personnel in telecom, data comm, computer, and semiconductor power electronics environments for: Power supplies (switching and linear) Semiconductor devices (SCRs, IGBTs, MOSFETs, CMOS, BJTs) Power inverters/converters Electronic ballasts The TCP300 and TCP400 Series AC/DC current measurement family is a highly advanced current measurement system for today s current Industrial/consumer electronics measurement needs. When connected to Tektronix oscilloscopes with Mobile communications (phone, satellite, relay stations) TEKPROBE Level II, TekConnect (w/ TCA-BNC), or TekVPI (w/ TPA-BNC) interfaces, current measurements and calculations are simple and easy. Motor drives Transportation systems (electronic vehicles, electric trains, Key performance specifications locomotives, avionics) DC - 100 MHz, Current Probe Amplifier (TCPA300) uses: DC - 100 MHz, 30 A DC (TCP312A) Meets today s AC/DC current measurement DC - 50 MHz, 50 A DC (TCP305A) applications DC - 15 MHz, 150 A DC (TCP303) The TCPA300 amplifier, when used with TCP312A, TCP305A, or TCP303 DC - 50 MHz, Current Probe Amplifier (TCPA400) Uses: probes, provides a wide range of current measurement capability and 1 DC - 2 MHz, 750 A DC (TCP404XL) (500 A DC Continuous) 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 Key features current levels, the TCPA400 amplifier with the TCP404XL current probe 2 Automatic scaling and units - Oscilloscope on-screen readout of measures 500 A DC continuous and 750 A DC continuous, derated with magnitude and amps reduces measurement errors with no more hand duty cycle. calculations Higher-frequency performance is available with the TCP312A w/TCPA300 AC/DC input coupling providing 100 MHz bandwidth and a maximum current of 30 A DC. Low insertion impedance reduces device under test loading Split-core construction allows easy circuit connection Status indicators provide visual operating status and notification of potential error conditions - degauss, probe open, overload, not terminated into 50 , noncompatible probe type 1 Derated with duty cycle 2 Requires a TDS TEKSCOPE oscilloscope or a TekConnect oscilloscope with TCA-BNC adapter www.tek.com 1Datasheet Measurement errors and manual calculations The TCP300/TCP400 current measurement systems seamlessly integrate are now a thing of the past with your TDS series oscilloscope. With this new series of current measurement tools, automatic control and Even non-TEKPROBE systems can use the TCPA300/400 series to make on-screen scaling and units is provided for users of Tektronix TDS3000, proper current measurements by simply multiplying the measured output TDS500, TDS600, TDS700, TDS5000, TDS6000, and TDS7000B series voltage on the oscilloscope by the TCPA300/400 series range setting. oscilloscope systems (the DPO3000, MDO/MSO/DPO4000, MSO/ DPO5000, and DPO7000 series oscilloscopes, the TPA-BNC adapter is required).
