action
The sweep measurement action; set to one of the following values:
0
or
smu
X
.DISABLE
: Do not make measurements during the sweep
1
or
smu
X
.ENABLE
: Make measurements during the sweep
2
or
smu
X
.ASYNC
: Make measurements during the sweep, but asynchronously
with the source area of the trigger model
X
Source-measure unit (SMU) channel (for example,
smua.trigger.measure.action
applies to SMU channel A)
Details
With this attribute enabled (setting
action
to
smu
X
.ENABLE
or
smu
X
.ASYNC
), configure the measurement with
one of the
smu
X
.trigger.measure.
Y
()
functions.
If this attribute is set to
smu
X
.ASYNC
:
•
Asynchronous sweep measurements can only be used with measure autoranging turned off. To turn
measure autoranging off for all measurements during the sweep, set the
smu
X
.measure.autorange
Y
attribute to
smu
X
.AUTORANGE_OFF
.
•
If the integrating ADC is selected (
smu
X
.measure.adc
attribute is set to
smuX.ADC_INTEGRATE
),
autozero must also be turned off. To turn off autozero, set the
smu
X
.measure.autozero
attribute to
smu
X
.AUTOZERO_OFF
or
smu
X
.AUTOZERO_ONCE
.
If either of the above items is incorrectly configured, the
smu
X
.trigger.initiate()
function generates an
error.
