Industry’s highest sensitivity, highest dynamic
range AC/DC current probes
As modern battery-powered devices and integrated circuits
become more ‘green’ and energy efficient, there is a
growing need to make low level, wide dynamic range current
measurements to ensure the current consumption of these
devices is within acceptable limits.
The new N2820A Series high-sensitivity current probes address
the need for high-sensitivity current measurements with a wide
dynamic range. These probes also offer the advantage of small
physical connections to the DUT because today’s application
environments require an extremely small form factor. The N2820A
Series probes have higher sensitivity – up to 200X greater than
existing clamp-on current probes with sub-milliampere low level
sensitivity.
