Setting the Offset Voltage or Common-Mode Voltage
An offset voltage can be added to the single-ended output of the PSIEVM or a common-mode voltage can
be added to the differential outputs.
shows the jumper combinations that are required to
implement an offset or common-mode voltage. Once the jumpers are placed in the correct configuration,
set the offset voltage or common-mode voltage through the GUI.
