Application Note Overview 

All models of the PSB, PSI, and ELR 10000 series feature an IU table function as part of the function generator. The IU table function (XY table) offers the user the ability to set a DC output current based on the DC voltage measured at the DC terminals. This feature works in either source or sink mode. The IU table function can be used to simulate a charging or discharging battery or to simulate a solar panel in PV related tests. Furthermore, the application note explains the different ways of controlling and uploading IU tables.
