Keithley Instruments has enhanced its popular ACS Basic Edition software, adding support for a broader line of source-measure (SMU) instrumentation. This broader choice of compatible instruments should prove especially useful in expanding the software’s voltage and current limits available for testing solar cells, photovoltaic panels, and discrete power semiconductors. ACS Basic Edition combines high speed hardware control, device connectivity, and data management into an easy-to-use tool optimized for part verification, debugging, and analysis.
