smuX.sense
X = SMU channel (a or b)
Attribute Remote/local sense mode.
Default smuX.SENSE_LOCAL
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage sense = smuX.sense -- Reads sense mode.
smuX.sense = sense -- Writes sense mode.
sense The sense mode.
Set sense to one of the following values:
0 or smuX.SENSE_LOCAL Selects local sense (2-wire).
1 or smuX.SENSE_REMOTE Selects remote sense (4-wire).
3 or smuX.SENSE_CALA Selects calibration sense mode.
Remarks • Source-measure operations are performed using either 2-wire local sense connections or 4-wire
remote sense connections. Writing to this attribute selects the sense mode.
• The smuX.SENSE_CALA mode is only used for calibration and may only be selected when
calibration is enabled.
• The sense mode can be changed between local and remote while the output is on.
• The calibration sense mode cannot be selected while the output is on.
• The reset function selects the local sense mode.
Details See Sensing methods in Section 2.
Example Selects remote sensing for SMU A:
smua.sense = smua.SENSE_REMOTE
smuX.source.autorangeY
X = SMU channel (a or b)
Y = SMU measure function (v or i)
Where: v = voltage, i = current
Attribute Source auto range control (on/off).
Default smuX.AUTORANGE_ON
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage sautorange = smuX.source.autorangev -- Reads voltage source auto range.
smuX.source.autorangev = sautorange -- Writes voltage source auto range.
sautorange = smuX.source.autorangei -- Reads current source auto range.
smuX.source.autorangei = sautorange -- Writes current source auto range.
sautorange The auto range status.
Set sautorange to one of the following values:
0 or smuX.AUTORANGE_OFF Disables source auto range.
1 or smuX.AUTORANGE_ON Enables source auto range.
Remarks • This attribute indicates the source auto range state. Its value will be smuX.AUTORANGE_OFF
when the SMU source circuit is on a fixed range and smuX.AUTORANGE_ON when it is in auto
range mode.
• Setting this attribute to smuX.AUTORANGE_OFF puts the SMU on a fixed source range. The fixed
range used will be the range the SMU source circuit was currently using.
• Setting this attribute to smuX.AUTORANGE_ON puts the SMU source circuit into auto range
mode. If the source output is on, the SMU will immediately change range to the range most
appropriate for the value being sourced if that range is different from the SMU range.
• Auto range will disable if the source level is edited from the front panel.
Details See Range in Section 6.
Also see smuX.measure.autorangeY, smuX.source.rangeY
Example Enables volts source auto range for SMU A:
smua.source.autorangev = smua.AUTORANGE_ON
