Abstract
Methods, systems, and computer readable media for measuring voltage and current waveforms at devices under test. An example method includes outputting an electrical signal from a signal generator of a measurement instrument; measuring a first voltage at an input to an output resistance of the measurement instrument; measuring a second voltage at an output of the output resistance of the measurement instrument; and determining a test measurement voltage at a device under test (DUT) electrically connected to the measurement instrument using the first voltage, the second voltage, and a propagation delay of a transmission line electrically connecting the measurement instrument to the DUT.
