02 Keysight N2780B Series AC/DC Current Probes A wide selection of current probes to meet your application’s needs - Data SheetHybrid technology for AC and DC measurementsUsing hybrid technology that includes a Hall-effect sensor and an AC currenttransformer, the probes provide accurate measurement of DC or AC currents upto 500 Arms (for model N2780B) or DC–100 MHz (for model N2783B), withoutbreaking into the circuit. Using split core construction, the probe easily clips onand off of a conductor.Figure 1. N2780B Series current probes withN2779A power supply–– Various bandwidths: DC to 2 MHz,10 MHz, 50 MHz, 100 MHz–– DC and AC measurements–– Superior 1% accuracy and highsignal-to-noise ratio–– O verload-protect functionprevents probe damage fromexcessive input–– Direct connection to highimpedance 1 MΩ BNC input ofoscilloscope–– “Demagnetize” button to removeany residual magnetism thatbuilds up in the magnetic core–– E xternal power supply (N2779A)lets you connect up to threeN278xB current probes to asingle power supplyCompatible with any oscilloscopewith a high-impedance BNC input,the new N2780B Series currentprobes offer accurate and reliablesolution for measuring DC and ACcurrents.Wide range of applicationsThe current probes feature broad measurement ranges (up to 500 A), flatfrequency response, low noise and low insertion loss that make the probes idealfor current measurements in areas such as measuring steady state or transientcurrent of motor drives, switching power supplies, inverters, controllers, sensors,disk drives, LCD displays, electronic ballasts and amplifiers. The high signal-tonoise ratio of the N2782B and N2783B makes them ideal for making low-levelcurrent measurements in milliampere ranges.Accurate current measurementA built-in DEMAG (demagnetize) function allows the removal of any residualmagnetism that has built up in the magnetic core due to power on/off switchingor excessive input current. In addition, voltage offset or temperature drift on theprobe can be easily corrected by using the zero adjustment control.Figure 2.
