Detailed Description Keysight N2821A High sensitivity 1 channel current probe manufacturers description

As modern battery-powered devices and integrated circuits become more green and energy efficient, there is a growing need to make high-sensitivity, low-level current measurements to ensure the current consumption of these devices is in acceptable limits. The N2821A high-sensitivity probe is engineered to make high-dynamic-range, high-sensitivity measurements to meet today’s challenging current measurement needs.


The ultra-sensitive N2821A AC/DC current probe can support measurements from 50 uA to 5 A on Keysight oscilloscopes. The N2821A interface uses a make-before-break (MBB) connector, allowing you to quickly probe multiple locations on your DUT without having to solder or unsolder the leads.


The N2820A 2-channel current probe connects to two oscilloscope channels to provide simultaneous low- and high-gain views for wider dynamic range measurement, while the N2821A 1-channel current probe provides one user-selectable view at a time.


Use in combination with the 9000 H-Series HD Infiniium oscilloscopes for the ultimate high-definition measurement solution. Use an area-under-the-curve measurement (Charge) on Infiniium oscilloscopes where you can easily calculate the integrated current consumptions over time in Coulombs.
