PXIe Source Measure Unit
S2020C
8-Channel PXIe SMU
The S2020C is a compact, highly integrated, single-slot, 8-channel PXIe Source/Measure Unit (SMU). It provides independent voltage and current sourcing and measurement on all eight channels concurrently. Each channel delivers up to ±10 V, ±200 mA output, featuring ultra-high voltage resolution of 1 μV, exceptional current resolution of 1 pA, and high-speed sampling up to 1 MS/s. It supports both DC and pulsed stimulus modes and complies with standard SMU SCPI commands to enable seamless test code migration, while maintaining compatibility with mainstream PXIe chassis.
The single-slot 8-channel architecture enables high-density parallel test configurations and supports multi-card synchronization. Its dense channel arrangement facilitates mid-power parallel test systems, improving test throughput and optimizing system footprint and overall cost.
Highlights
  • Higher current drive
    Operates on a ±10 V platform with current drive capability up to ±200 mA
  • Minimum-range accuracy
    ±0.6 V range: accuracy of 0.02% + 50 μV
    ±1 μA range: accuracy of 0.05% + 300 pA
  • High resolution
    The minimum measurement resolution can reach 0.1 fA / 100 nV
  • High sampling rate
    Up to 1MS/s ADC sampling rate
  • Adaptive APFC control
    Adjusts APFC parameters based on load characteristics to balance fast settling and low overshoot
  • Enhanced 4-wire measurement
    Covers 100 Ω – 1 MΩ with 1 μV / 1 pA resolution for high-accuracy resistance measurement
  • Protection
    Overtemperature shutdown
    Red LED alerts for overcurrent and overvoltage
    Hardware reset for rapid recovery
