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.

Key Features
- Ultra-Low Noise Output: Features a noise floor as low as 3 μVp-p, ideal for sensitive applications like quantum qubit testing and high-speed ADC characterization.
- Four-Quadrant Operation: Operates as both a precision power source and a current sink (load) up to 30V/200mA without hardware changes.
- USB Mass Storage Integration: Internal 4MB memory is recognized as an external drive by PCs, simplifying the management of CSV patterns for complex sweep testing.
- Bipolar Output Polarity: Polarity changes are executed electronically without mechanical relay chatter, preventing voltage spikes during transitions.
