ac/dc current measurement systems tcpa300, tcp312a, tcp305a, TCP303, tcpa400, tcp404xl datasheet the tcp300 and tcp400 series ac/dc current measurement family 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. key performance specifications dc - 100 mhz, current probe amplifier (tcpa300) uses: dc - 100 mhz, 30 a dc (tcp312a) dc - 50 mhz, 50 a dc (tcp305a) dc - 15 mhz, 150 a dc (TCP303) dc - 50 mhz, current probe amplifier (tcpa400) uses: dc - 2 mhz, 750 a dc 1 (tcp404xl) (500 a dc continuous) 1 derated with duty cycle key features automatic scaling and units 2 - oscilloscope on-screen readout of magnitude and amps reduces measurement errors with no more hand calculations ac/dc input coupling 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 low dc drift and noise allows improved low-level current measurements 3rd party safety certification 2 requires a tds tekscope oscilloscope or a tekconect oscilloscope with tca-bnc adapter 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 industrial/consumer electronics mobile communications (phone, satellite, relay stations) motor drives transportation systems (electronic vehicles, electric trains, locomotives, avionics) meets today's ac/dc current measurement applications 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. specifications all specifications apply to all models unless noted otherwise. model overview tcp312a w/ tcpa300 tcp305a w/ tcpa300 TCP303 w/ tcpa300 tcp404xl w/ tcpa400 bandwidth dc C 100 mhz dc C 50 mhz dc C 15 mhz dc C 2 mhz rise time 3.5 ns 7 ns 23 ns 175 ns dc accuracy 3% of reading 3% of reading 3% of reading 3% of reading dc accuracy, typical 1% of reading 1% of reading 1% of reading 1% of reading lowest measurable current (at 3% accuracy at dc) scope set to 1 mv/div and 20 mhz bw limited 1 ma 5 ma 5 ma 1 a maximum amp-second product, typical (based on amplifier range setting) 50 a*s C 1 a/v 500 a*s C 10 a/v 500 a*s C 5 a/v na C 10 a/v 3,000 a*s C 5 a/v 15,000 a*s C 50 a/v na C 1 a/mv maximum wire voltage, bare insulated 150 v cat ii 300 v cat ii 150 v cat ii 300 v cat ii 600 v cat i & ii 300 v cat iii 600 v cat i & ii 300 v cat iii ac-coupling low-frequency bandwidth, typical (low pass C 3 db point) <7 hz <7 hz <7 hz <7 hz displayed rms noise, typical (at 20 mhz bandwidth limit) 250 a rms 1.25 ma rms 2.5 ma rms 250 ma rms signal delay (to output bnc) 17 ns 19 ns 40 ns 80 ns insertion impedance 0.11 ? at 1 mhz 0.12 ? at 10 mhz 0.35 ? at 50 mhz 0.7 ? at 100 mhz 0.02 ? at 1 mhz 0.1 ? at 10 mhz 0.35 ? at 50 mhz 0.01 ? at 1 mhz 0.025 ? at 5 mhz 0.1 ? at 15 mhz 0.1 m ? at 10 khz 0.6 m ? at 100 khz 8 m ? at 1 mhz 16 m ? at 2 mhz datasheet 2 www.tektronix.com
