Details
When making measurements, the SMU uses one of two types of analog-to-digital converters. This attribute
controls which analog to converter is used.
Example
smua.measure.adc = smua.ADC_FAST
Selects the fast A/D converter for SMU
channel A.

autoRange
The state of the measurement autorange setting; set to one of the following values:
0
or
smu
X
.AUTORANGE_OFF
: Disabled
1
or
smu
X
.AUTORANGE_ON
: Enabled
2
or

X
.AUTORANGE_FOLLOW_LIMIT
: Measure range automatically set to the limit
range
X
Source-measure unit (SMU) channel (for example,
smua.measure.autorangev
applies to SMU channel A)
Y
SMU measure function (
v
= voltage,
i
= current)
Details
This attribute indicates the measurement autorange state. Its value is
smu
X
.AUTORANGE_OFF
when the SMU
measure 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 range. The fixed range is the present
SMU measure range.
Setting this attribute to
smu
X
.AUTORANGE_ON
puts the SMU measure circuit in autorange mode. It remains on
its present measure range until the next measurement is requested.
Example
smua.measure.autorangev = 1
Enables voltage measurement autoranging for SMU
channel A. Alternatively, the value 1 may be replaced with
smua.AUTORANGE_ON
.
