Pico Technology AD2201 Active Differential Probe

Overview

The Pico Technology AD2201 is a 200 MHz bandwidth active differential probe designed for high-speed measurement applications requiring safe and accurate differential voltage measurements. This probe extends the functionality of standard single-ended input oscilloscopes, allowing measurement of differential signals with a ±20 V differential range and a common-mode range of up to ±60 V DC + peak AC. The redesigned probe includes improved powering options with in-line battery module and integrated 5 V USB power for use with standard USB chargers.
