Safety Information 28
The N2820A and N2821A high- sensitivity current probes
allow you to measure AC and DC currents from 50 μA to
5A. These high dynamic- range probes are designed to be
used on devices that have very tight geometry constraints.
Since these probes do not need to be degaussed and do not
require frequent calibration, you can focus on making your
measurements. The probes accurately construct the current
waveform by measuring the voltage across an R
SENSE
resistor,
which results in highly repeatable measurements.
CAUTION Before using the probe, refer to “Safety Information” on page 28.
