S4g#
Description#
The S4g is a 4 channel DC current source. Each channel is controlled by the same 18-bit DACs (Digital to Analog Converters).
On the front of each S4g module you find:
4 x SMA: DC current source with software-selectable range: ±50 mA, ±25 mA, +50 mA, 18-bit resolution, 40 Ω output impedance.
4 x MCX: Voltage monitor for each channel.
4 x LED: To indicate that the current source is clipping to its compliance voltage.
