The Keysight E4366A is a configurable Solar Array Simulator (SAS) mainframe that accepts up to two E436xA DC power modules to accurately replicate solar array output characteristics. This 2U-height system delivers fast I-V curve simulations across varying environmental conditions, making it essential for spacecraft power system validation, solar panel qualification, and eclipse/thermal transient testing. The modular architecture accommodates multiple DC sources in a compact footprint while standard interfaces—LAN, USB, and GPIB—enable remote operation and integration into automated test environments.
