The mainframe contains two E4362A modules:

The E4368A is a preconfigured solar array simulator consisting of one E4360A mainframe and two E4362A modules. It is shipped as fully tested and assembled dual output solar array simulator. The Keysight E4362A is a 600W solar array simulator DC power module that simulates the output characteristics of a solar array. The E4361A is primarily a current source with very low output capacitance. It offers fast I-V curve changes allowing you to accurately simulate the output of different solar arrays under various environmental conditions (ex. temperature, age, eclipse, spin etc.).

Additionally, the E4360A SAS mainframe saves valuable rack space with its 2U high size. LAN, USB, and GPIB interfaces are standard. To simplify test system software development, the 14360A System Control Tool software package is shipped free with every E4360A SAS mainframe. This software simplifies the programming and control of multiple SASs. It allows a single function call to setup and control up to 100 E4360 outputs in a SAS system.

The E4360 SAS is available as a standalone off-the-shelf instrument and is also available from Keysight integrated into a full turn key solar array simulator system configured to your exact specification with all the instruments and the software integrated and installed.
