PXIe Source Measure Unit
S2021C
4-Channel PXIe SMU

The S2021C is a compact, highly integrated, single-slot, 4-channel PXIe Source/Measure Unit (SMU). It provides independent voltage and current sourcing and measurement across all four channels concurrently. Each channel delivers up to ±8 V, ±5 A, 40 W high-power output, with a maximum total power of 45 W shared among four channels for flexible dynamic power allocation. It features ultra-high voltage resolution of 100 nV, exceptional current resolution of 100 fA, and high-speed sampling up to 1 MS/s. The module supports multi-card synchronous triggering, complies with standard SMU SCPI commands and offers multi-language programming interfaces to enable streamlined test code migration, while maintaining compatibility with mainstream PXIe chassis.
