The Keysight 1147B is a wide bandwidth, active current probe compatible with InfiniiVision and Infiniium oscilloscopes. It features a DC to 50 MHz bandwidth, provides a high signal-to-noise ratio, and is capable of measuring low current levels. The probe supports peak currents of 15A, 30A for short durations, and continuous currents of 10A. It includes safety features such as an over-input protection function and a demagnetizing switch to eliminate residual magnetism in the magnetic core. The probe is compatible with high impedance AutoProbe interfaces and is suitable for applications in sensing and instrumentation, metering, and test and measurement.
