Usage
highC = smua.source.highc
smua.source.highc = highC
highC
The state of the high-capacitance mode; set to one of the following values:
▪ 0 or smua.DISABLE: Disables high-capacitance mode
▪ 1 or smua.ENABLE: Enables high-capacitance mode
Details
When enabled, the high-capacitance mode has the following effects on the SMU settings:
• smua.measure.autorangei is set to smua.AUTORANGE_FOLLOW_LIMIT and
cannot be changed
• Current ranges below 1 µA are not accessible
• If smua.source.limiti is less than 1 µA, it is raised to 1 µA
• If smua.source.rangei is less than 1 µA, it is raised to 1 µA
• If smua.source.lowrangei is less than 1 µA, it is raised to 1 µA
• If smua.measure.lowrangei is less than 1 µA, it is raised to 1 µA
High-capacitance mode is not available when the pulser is enabled.
Example
smua.source.highc = smua.ENABLE
Activates high-capacitance mode.
