Abstract
A measurement apparatus is provided that measures a current signal Ithat flows through a device under test. A transimpedance amplifier converts the current signal Iinto a voltage signal V. A digitizer converts the voltage signal Vinto first digital data. A digital signal processing unit performs signal processing on the first digital data, and controls the measurement apparatus. The measurement apparatus has a configuration comprising two separate modules, i.e., a probe module which is located in the vicinity of the device under test during a measurement, and a backend module connected to the probe module via at least one cable. The transimpedance amplifier is built into the probe module.
