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 ±32 V and ±200 mA.
During sink operation, the GS200 operates in the same quadrants as it does during
source operation, so you can use it not just as a true constant voltage source but also as
a highly accurate electronic load.

Bipolar Output
Because the GS200 inverts the signal polarity and produces the signal without the use
of a mechanical contact, no abnormal voltage (or current) is generated when the polarity
is inverted. Therefore, the GS200 can generate continuous, variable output ranging
from the maximum negative value to the maximum positive value. This is effective when
you want to invert the polarity to generate program output or evaluate zero-crossing
comparators. Additionally, when you change settings within the same range, glitches are
not generated.
