Abstract: Apparatuses of a noise measurement system and methods for using the same are disclosed. In one embodiment, a noise measurement system may include a plurality of probe groups electrically coupled to a plurality of DUTs, where a probe group in the plurality of probe groups includes multiple channels, and where the multiple channels of each probe group are bundled as a group for reducing electromagnetic interference among the plurality of probe groups, and wherein the group is shielded from corresponding signal groups of other DUTs with a connection to a circuit ground of the noise measurement system for reducing ground loop generated signal interference. The noise measurement system may further include a controller configured to perform noise measurement.
