A wide selection of current probes to meet your application’s needs

• Various bandwidths: DC to 2 MHz, 10 MHz, 50 MHz, 100 MHz
• DC and AC measurements
• Superior 1% accuracy and high signal-to-noise ratio
• Overload-protect function prevents probe damage from excessive input
• Direct connection to high- impedance 1 MΩ BNC input of oscilloscope
• “Demagnetize” button to remove any residual magnetism that builds up in the magnetic core
• External power supply (N2779A) lets you connect up to three N278xB current probes to a single power supply

Compatible with any oscilloscope with a high-impedance BNC input, the new N2780B Series current probes offer accurate and reliable solution for measuring DC and AC currents.

Hybrid technology for AC and DC measurements

Using hybrid technology that includes a Hall-effect sensor and an AC current transformer, the probes provide accurate measurement of DC or AC currents up to 500 Arms (for model N2780B) or DC–100 MHz (for model N2783B), without breaking into the circuit. Using split core construction, the probe easily clips on and off of a conductor.

Wide range of applications

The current probes feature broad measurement ranges (up to 500 A), flat frequency response, low noise and low insertion loss that make the probes ideal for current measurements in areas such as measuring steady state or transient current of motor drives, switching power supplies, inverters, controllers, sensors, disk drives, LCD displays, electronic ballasts and amplifiers. The high signal-to- noise ratio of the N2782B and N2783B makes them ideal for making low-level current measurements in milliampere ranges.

Accurate current measurement

A built-in DEMAG (demagnetize) function allows the removal of any residual magnetism that has built up in the magnetic core due to power on/off switching or excessive input current. In addition, voltage offset or temperature drift on the probe can be easily corrected by using the zero adjustment control.

Compatible Oscilloscopes

Any oscilloscope offering 1 MΩ BNC input including Keysight Technologies, Inc. 1000, 3000 InfiniiVision 2000X,3000X, 5000, 6000 and 7000 Series, and Infiniium 8000 and 9000 Series. You must select the input impedance of the oscilloscope to be 1 MΩ in order to make accurate measurements. If the oscilloscope you are using has a 50Ω input impedance setting only, you can purchase the Keysight E2697A 50Ω to 1 MΩ adapter for use with the Infiniium 80000 or 90000 Series or the N5449A high impedance probe adapter for use with the Infiniium 90000 X-Series.
