The Keysight E4350B One-Box Solar Array Simulator (SAS) is a dc power source with 480 watt output that simulates the output characteristics of a solar array. The SAS is primarily a current source with very low output capacitance and is capable of simulating the I-V curve of different arrays under various conditions. The I-V curve is programmable over the IEEE-488.2 bus and is conveniently generated within the SAS. Up to 60 volatile / non-volatile tables can be pre-programmed.
