ETA5540B AC / DC current probe

The current probe can detect the current flowing through the conductor and convert it into a voltage that can be seen and measured on an oscilloscope. The current probe uses a hybrid technology including a Hall-effect sensor (induction of direct current) and a current transformer (induction of alternating current). The open-ended design of the current probe is easy to connect and disconnect with the conductor, providing a measurement bandwidth from DC to 100 MHz.
