applicationsdevelopment and analysis solutions for designers, installers, andservice personnel in telecom, data comm, computer, andsemiconductor power electronics environments for:
power supplies (switching and linear)semiconductor devices (scrs, igbts, mosfets, cmos, bjts)power inverters/converterselectronic ballastsindustrial/consumer electronicsmobile communications (phone, satellite, relay stations)motor drivestransportation systems (electronic vehicles, electric trains,locomotives, avionics) 
meets today's ac/dc current measurement applicationsenter a short description of your concept here (optional).
the tcpa300 amplifier, when used with tcp312a, tcp305a, or tcp303probes, provides a wide range of current measurement capability andspans the gap between low-level milliamp measurements to very highcurrent levels. these three probes provide current measurementcapabilities of 30 a, 50 a, and 150 a dc continuous.for even higher current levels, the tcpa400 amplifier with thetcp404xl current probe measures 500 a dc continuous and750 a dc continuous, derated with duty cycle.
higher-frequency performance is available with the tcp312aw/tcpa300 providing ≥100 mhz bandwidth and a maximum currentof 30 a dc.
measurement errors and manual calculations are now a thing of thepastenter a short description of your concept here (optional).
with this new series of current measurement tools, automaticcontrol and on-screen scaling and units is provided for users oftektronix tds3000, tds500, tds600, tds700, tds5000, tds6000, andtds7000b series oscilloscope systems (the dpo3000, mdo/mso/dpo4000,mso/dpo5000, and dpo7000 series oscilloscopes, the tpa-bnc adapteris required).
the tcp300/tcp400 current measurement systems seamlessly integratewith your tds series oscilloscope.
even non-tekprobe systems can use the tcpa300/400 series tomake proper current measurements by simply multiplying the measuredoutput voltage on the oscilloscope by the tcpa300/400 seriesrange setting.
