Usage
highC
= smu
X
.source.highc
smu
X
.source.highc =
highC
highC
The state of the high-capacitance mode; set to one of the following values:
0
or
smu
X
.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:
•
smu
X
.measure.autorangei
is set to
smu
X
.AUTORANGE_FOLLOW_LIMIT
and cannot be changed
•
Current ranges below 1
μ
A are not accessible
•
If
smu
X
.source.limiti
is less than 1
μ
A, it is raised to 1
μ
A
•
If
smu
X
.source.rangei
is less than 1
μ
A, it is raised to 1
μ
A
•
If
smu
X
.source.lowrangei
is less than 1
μ
A, it is raised to 1
μ
A
•
If
smu
X
.measure.lowrangei
is less than 1
μ
A, it is raised to 1
μ
A
Example
smua.source.highc = smua.ENABLE
Activates high-capacitance mode
for SMU channel A.
