Overview<\/h2>\n

The Keysight N2780B AC\/DC Current Probe is a high-performance clamp-on current probe designed for accurate measurement of both AC and DC currents in electronic and power systems. Utilizing a hybrid sensing technology that combines a Hall-effect sensor with an AC current transformer, the probe delivers precise and stable current measurements without breaking the circuit.<\/p>\n

With a bandwidth of DC to 2 MHz and a continuous current capability of up to 500 Arms, the N2780B is ideal for analyzing both steady-state and dynamic current behavior in modern electronic systems.<\/p>\n
