smuX.source.func
X = SMU channel (a or b)
Attribute
Source function.
Default
smuX.OUTPUT_DCVOLTS
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
iv = smuX.source.func
-- Reads source function.
smuX.source.func = iv
-- Writes source function.
iv
The source function.
Set
iv
to one of the following values:
0
or
smuX.OUTPUT_DCAMPS
Selects current source function.
1
or
smuX.OUTPUT_DCVOLTS
Selects voltage source function.
Remarks
• Reading this attribute gives the output function of the source. Setting this attribute configures the
SMU as either a voltage source or a current source.
• The
reset
function selects the voltage function.
Details

Example
Selects the source amps function for SMU A:
smua.source.func = smua.OUTPUT_DCAMPS
smuX.source.highc
X = SMU channel (a or b)
Attribute
High capacitance mode.
Default
smuX.DISABLE
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
highc = smuX.source.highc
-- Reads the High-C setting.
smuX.source.highc = highc
-- Writes the High-C mode.
highc
The
High-C
mode.
Set
highc
to one of the following values:
1
or
smuX.ENABLE
Turns on high capacitance mode.
0
or
smuX.DISABLE
Turns off high capacitance mode.
Remarks
• Turning on High-C 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 1uA are not accessible
•
If
smuX.source.limiti
is less than 1uA, it is raised to 1uA.
•
If
smuX.source.rangei
is less than 1uA, it is raised to 1uA.
•
If
smuX.source.lowrangei
is less than 1uA, it is raised to 1uA.
•
If
smuX.measure.lowrangei
is less than 1uA, it is raised to 1uA.
Details

Example
Activate high capacitance mode for SMU A:
smua.source.highc = smua.ENABLE
