Usage
:SOURce[1]:<function>:HIGH:CAPacitance <state>
:SOURce[1]:<function>:HIGH:CAPacitance?
The source function to which this setting applies:
• Current: CURRent
• Voltage:
Turn high capacitance off: OFF or 0
Turn high capacitance on: ON or 1
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 mode to minimize these
problems.
The settings for high-capacitance mode apply when you operate the instrument using the 1 µA and
above 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.
Use this command with limited autorange (low) with the low range set to 1 µA.
Example
Turn the high capacitance mode on when
sourcing current.
