sourceAutorange
The state of the source autorange control. Set to one of the following:
0
or
smu
X
.AUTORANGE_OFF
: Disables source autorange
1
or
smu
X
.AUTORANGE_ON
: Enables source autorange
X
Source-measure unit (SMU) channel (for example,
smua.source.autorangev
applies to SMU channel A)
Y
SMU source function (
v
= voltage,
i
= current)
Details
This attribute indicates the source autorange state. Its value will be
smu
X
.AUTORANGE_OFF
when the
SMU source circuit is on a fixed range and
smu
X
.AUTORANGE_ON
when it is in autorange mode.
Setting this attribute to
smu
X
.AUTORANGE_OFF
puts the SMU on a fixed source range. The fixed
range used will be the present SMU source circuit range.
Setting this attribute to
smu
X
.AUTORANGE_ON
puts the SMU source circuit into autorange 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 present SMU range.
Autorange will disable if the source level is edited from the front panel. Setting the source range turns
off autorange when set by using the
smu
X
.source.range
Y
attribute as well.
Resetting the instrument selects the
smu
X
.AUTORANGE_ON
.
Example
smua.source.autorangev = smua.AUTORANGE_ON
Enables volts source autorange for
SMU channel A.
