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.
If source highC mode is enabled, current autorange is set to
smu
X
.AUTORANGE_FOLLOW_LIMIT
and cannot be
changed.
Example
smua.measure.autorangev = 1
Enables voltage measurement autoranging for SMU
channel A. Alternatively, the value 1 may be replaced with
smua.AUTORANGE_ON
.

Indicates status of autozero; set to one of the following values:
0
or
smu
X
.AUTOZERO_OFF
: Autozero disabled
1
or
smu
X
.AUTOZERO_ONCE
: Performs autozero once, then disables autozero
2
or
smu
X
.AUTOZERO_AUTO
: Automatic checking of reference and zero
measurements; an autozero is performed when needed
X
Source-measure unit (SMU) channel (for example,
smua.measure.autozero
applies to SMU channel A)
