Usage
highC = smuX.source.highc
smuX.source.highc = highC
highC
The state of the high-capacitance mode; set to one of the following values:
0 or smuX.DISABLE: Disables high-capacitance mode
1 or smu
X
.ENABLE: Enables high-capacitance mode
X
Source-measure unit (SMU) channel (for example, smua.source.highc applies
to SMU channel A)
Details
When enabled, the high-capacitance mode has the following effects on the SMU settings:
• smuX.measure.autorangei is set to smuX.AUTORANGE_FOLLOW_LIMIT and cannot be changed
• Current ranges below 1 µA are not accessible
• If smuX.source.limiti is less than 1 µA, it is raised to 1 µA
• If smuX.source.rangei is less than 1 µA, it is raised to 1 µA
• If smuX.source.lowrangei is less than 1 µA, it is raised to 1 µA
• If smuX.measure.lowrangei is less than 1 µA, it is raised to 1 µA
Example
smua.source.highc = smua.ENABLE
Activates high-capacitance mode
for SMU channel A.

Usage
sourceLevel = smuX.source.levelY
smuX.source.levelY = sourceLevel
sourceLevel
The source value; set to one of the following values:
Voltage: 0 V to ±40 V (Models 2601B/2602B/2604B)
Voltage: 0 V to ±200 V (Models 2611B/2612B/2614B/2634B/2635B/2636B)
Current: 0 A to ±3 A (Models 2601B/2602B/2604B)
Current: 0 A to ±1.5 A (Models 2611B/2612B/2614B/2634B/2635B/2636B)
X
Source-measure unit (SMU) channel (for example, smua.source.levelv applies
to SMU channel A)
Y
SMU source function (v = voltage, i = current)
