Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The CT6711 is a 3-range, high-sensitivity current probe that offers a wide DC to 120 MHz bandwidth and 200 μA to 30 A input, letting your capture signals across an expansive current range, from steady state to transient currents, when developing switching power supplies, inverters, and motor controllers.
