sFunction
The source function; set to one of the following values:
0
or
smu
X
.OUTPUT_DCAMPS
: Selects the current source function
1
or
smu
X
.OUTPUT_DCVOLTS
: Selects the voltage source function
X
Source-measure unit (SMU) channel (for example,
smua.source.func
applies to
SMU channel A)
Details
Reading this attribute indicates the output function of the source for the specified SMU channel.
Setting this attribute configures the specified SMU channel as either a voltage source or a current
source.
Example
smua.source.func = smua.OUTPUT_DCAMPS
Sets the source function of SMU
channel A to be a current source.

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
