The GS200 is a low voltage/current DC source with high accuracy, high stability, and high resolution. With its excellent traceability, stability, and 5 1/2-digit resolution, the GS200 generates extremely low-noise DC voltage and current signals that are required for many applications. Additionally, the optional monitoring feature turns the GS200 into a voltage and current measuring instrument.

High Accuracy and High Resolution Output

Each DC voltage/current source in the GS200 series uses two DACs to generate highly accurate voltage and current at a high resolution. It is highly stable whether it is used for a short or long period of time and features superb linearity over all the ranges. Moreover, it produces extremely low noise.

High accuracy:

±0.016% of setting + 240 μV (at 10 V range for one year)
±0.03% of setting + 5 μA (at 100 mA range for one year)

High stability:

±0.001% of setting 20 μV (at 10 V range for one day)
±0.004% of setting + 3 μA (at 100 mA range for one day)

High resolution:

100 nV (VDC, 10 mV range)
10 nA (1 mA range)

Low noise:

100 μVp-p (10 V range, DC to 10 kHz)
3 μAp-p (100 mA range, DC to 10 kHz)

The GS200 features 5 1/2-digit, ±120,000-count output resolution for both voltage and current sources. At the 100 mV and 10 mV source ranges, the GS200 uses its highly accurate voltage divider to achieve extremely low noise levels, in the order of μV. The minimum output resolution of 100 nV and low noise output enable you to make extremely small changes to the signal level.

Source and Sink Operations

The GS200 can perform four-quadrant operation by operating as a current source or a current sink in the range of ±30 V and ±200 mA.
When the GS200 is sinking current, it can operate over the exact same range as when it is operating as a current source. You can use the GS200 not just as a highly accurate voltage source but also as a highly accurate constant-current electronic load.

Voltage ranges: 10 mV, 100 mV, 1 V, 10 V, and 30 V
Maximum output current: ±200 mA (at 1 V, 10 V, and 30 V ranges)
(A highly accurate voltage divider is used at the 10 mV and 100 mV ranges.)
Current ranges: 1 mA, 10 mA, 100 mA, and 200 mA
Maximum output voltage: ±30 V

Seamless Bipolar Output

The GS200 bipolar output function inverts the signal polarity without the use of a mechanical contact. Thus, no abnormal voltage (or current) is generated when the polarity is inverted. This achieves truly continuous voltage variation from the maximum negative output to the maximum positive output. This feature is invaluable in the evaluation of zero-crossing comparators and in the output polarity inversion during program operation. Voltage or current glitches do not occur when the setting is changed within the same range.
