02 | Keysight | N2780B Series AC/DC Current Probes A wide selection of current probes to meet your application’s needs - Data Sheet

– 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.
