Details
When the instrument is measuring low current and is driving a capacitive load, you may see overshoot, ringing,
and instability. You can enable the high capacitance feature to minimize these problems.
High-capacitance settings apply when operating using the 10 nA through the 100 mA current ranges. When
operating using the 1 A range, the high-capacitance setting will not affect the instrument rise time or current
measure settling time.
Example
smu.source.highc = smu.ON
Turn the high capacitance feature on.
