S2024H

24-Channel Precision Source Meter

The Semight S2024H is a compact and cost-effective 24 channel desktop power supply/measurement unit (SMU) that can simultaneously output and measure voltage and current, providing maximum ± 4.5V, ± 10 mA (DC/pulse) output, and excellent color LCD graphical user interface (GUI).

  • High range – Range: ± 4.5 V, ± 10 mA (DC)
  • High resolution – The minimum measurement resolution can reach 10 pA/1 μV
  • High sampling rate – Supports up to 1M ADC sampling rate
  • Threshold trigger – Hardware high-speed IO, capable of threshold triggering, enabling efficient interaction between output measurement values and user systems
