Abstract
A probe for a measurement instrument comprises an input terminal configured to receive an input signal from a device under test (DUT), an output terminal configured to transmit an output signal to a measurement instrument, and a clamping circuit disposed in a signal path between the input terminal and the output terminal and configured to clamp an internal probe signal between an upper clamping threshold and a lower clamping threshold to produce the output signal, wherein the clamping circuit operates with substantial gain and amplitude linearity throughout a range between the upper clamping threshold and the lower clamping threshold.
