# Tektronix TCP0150 150 A AC/DC Current Probe # Tektronix TCP0150 150 A AC/DC Current Probe ## Key Features At A Glance - DC to 20 MHz bandwidth (-3 dB) for AC/DC current measurements - 150 ARMS maximum current with 500 A peak pulse capability - Selectable 25 A and 150 A current ranges; measures down to 5 mA - DC accuracy typically ±1% gain error (3% warranted) - Connects directly to oscilloscopes with the TekVPI probe interface - Remote GPIB/USB probe control through the oscilloscope for automation - Split-core probe head with easy degauss and autozero - Automatic units scaling and readout on the oscilloscope display The Tektronix TCP0150 is a high-performance, easy-to-use 150 A AC/DC current probe designed for direct connection to the TekVPI probe interface. It measures both AC and DC current and provides automatic units scaling and readout on the oscilloscope's display, with setup controls, probe status, and diagnostic indicators available on both the probe hardware and through the oscilloscope's UI menu. Listed applications for the TCP0150 include power supplies, semiconductor devices, power inverters and converters, electronic ballasts, industrial and consumer electronics, motor drives, and transportation systems. A current probe of this type clamps around a conductor to measure the current flowing through it without breaking the circuit. That combination of real inventory and hands-on verification is how we stand behind what we sell. ## Accessories Supplied - Protective cover (016-1924-xx) - Certificate of traceable calibration and data standard ## Product Core & Specifications Specification Value Warranted characteristics Bandwidth DC to ≥20 MHz (-3 dB).
