Yokogawa GS200 DC Voltage/Current Source (GS210-7) 100 VAC The Yokogawa GS200 (Model GS210-7) is a low-noise, high-precision DC voltage and current source engineered for demanding electronic characterization and calibration tasks. Operating on 100 VAC (50/60 Hz), this unit provides the exceptional stability and 5.5-digit resolution required for semiconductor testing, quantum computing research, and high-accuracy sensor calibration. The GS200 series represents a significant advancement in DC source technology. Utilizing dual Digital-to-Analog Converters (DACs), it achieves a voltage resolution of 100 nV and a current resolution of 10 nA. Unlike standard power supplies, the GS200 functions as both a high-accuracy source and a constant-current electronic load (sink), allowing for seamless four-quadrant operation. Additionally, its integrated USB mass storage feature allows users to manage up to 10,000 programmable steps as simple files via a PC.
