Abstract

A measurement probe comprises at least one input port configured to receive an input signal generated in relation to a device under test (DUT), and an amplification unit configured to amplify the input signal with a first gain where the input signal has a first amplitude, and further configured to amplify the input signal with a second gain lower than the first gain where the input signal has a second amplitude greater than the first amplitude.
