- 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 N278x current probes to a single power supply
The N277xA Series will be discontinued soon.
Please visit their replacements' product page: Keysight N278xB AC/DC Current Probes.
Compatible with any oscilloscope with a high-impedance BNC input, the new N2780A 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 N2780A) or DC to 100 MHz (for model N2783A), 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 N2782A and N2783A 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.
The Keysight N2779A Power Supply (required) provides clean dc power for the N2780A/81A/82A/83A current probe. Three 12 V outputs allow for up to three N2780As to be connected enabling you to make effective three phase power measurements.
