High-Resolution Source Measurement Unit Series
High precision × multi-channel × fast response from 1fA/1μV — The ideal device for research and mass production.
A benchtop SMU (Source Measure Unit) series that balances precision measurement and high-performance output, ideal for research and development and reliability testing. Semight's high-resolution SMU products cover a wide range of voltage and current, from ±200V/±1A (DC) to ±3A (pulse), and even up to ±60V/±10A (pulse), achieving measurement resolutions from a maximum of 1fA/1μV to 10fA/100nV. Equipped with a maximum ADC sampling rate of 1MS/s and a self-developed high-precision, fast-response control system (Adaptive PFC), it supports a wide range of applications from accurate measurement of small signals to high-speed pulse testing.
