Yokogawa GS200 programmable DC voltage/current source

The GS200 programmable DC voltage/current source generates low-noise DC voltage and current signals for a range of device driving and testing applications, while an optional monitoring feature turns it into a voltage and current measuring instrument.

The 5½-digit resolution instrument claims high accuracy, high stability and high resolution. It will act as a voltage source up to ±32 V and a current source up to ±200 mA.

Features include a programmable output up to 10,000 steps of output values, built-in USB mass storage device and optional ethernet interface.

The instrument can perform four-quadrant operation by operating as a current source or a current sink. The optional voltage and current monitoring feature allows the instrument to function as a current monitor while generating voltage and as a voltage monitor while generating current.

Applications include usage as a DC voltage/current reference or pulse voltage/current source, pulse current driving for LEDs and organic EL displays, charge/discharge characteristics tests on batteries, ‘pass/fail’ component testing and the evaluation of zero-crossing comparators.
