Return to
smuX.sense
X = SMU channel (a or b)
Attribute
Remote/local sense mode.
Usage
sense = smuX.sense
-- Reads sense mode.
smuX.sense = sense
-- Writes 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.

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).
Usage
sautorange = smuX.source.autorangeY
-- Reads source auto range.
smuX.source.autorangeY = sautorange
-- Writes source auto range.
Set
autorange
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.
