The Tektronix TCP0030A is a high-bandwidth AC/DC current probe for engineers who need accurate current waveform visibility on TekVPI oscilloscopes. It delivers DC to >120 MHz bandwidth, 1 mA minimum current sensitivity, 30 A RMS, and up to 50 A peak pulse capability for fast transient and low-level current measurements. This model is the strongest fit in the group for switching power supplies, semiconductor testing, inverters, and other applications where bandwidth and low-current detail matter most.
Best for highest bandwidth and lowest current sensitivity in this group.
