Details
Use this attribute to perform extended operating area (EOA) pulse mode sweeps.
If this attribute is set to smua.LIMIT_AUTO (or 0), the SMU uses the normal limit setting during
sweeping. If this attribute is set to any other numeric value, the SMU switches in this limit at the start
of the source action and returns to the normal limit setting at the end of the end pulse action.
Normally, the limit range is automatically adjusted in accordance with the limit value. During
sweeping, however, the limit range is fixed to avoid the delays associated with changing range. This
fixed limit range is determined by the maximum limit value needed during the sweep; that is, the
greater of either the normal limit value (as specified by smua.source.limitY) or the sweep limit
value (as specified by smua.trigger.source.limitY). Note that the minimum limit value that can
be enforced during the sweep is equal to 10% of the full scale value of the fixed limit range. If the
smaller limit value (normal or sweep) falls below this 10% threshold, the 10% value is enforced
instead. Likewise, if the limit value falls below the 10% threshold as a result of power compliance, the
10% value is enforced instead.
When using the EOA, the SMU will automatically start the end pulse action if the SMU is not triggered
before its maximum pulse width. It will also delay the source action if necessary to limit the pulse duty
cycle to stay within the capabilities of the SMU.
Example
smua.trigger.source.limitv = 10
Sets the voltage sweep limit to 10 V.

Usage
smua.trigger.source.linearY(startValue, endValue, points)
Y
SMU source function (v = voltage, i = current)
startValue
Source value of the first point
endValue
Source value of the last point
points
The number of points used to calculate the step size
Details
This function configures the source action to be a linear source sweep in a subsequent sweep. During
the sweep, the source will generate a uniform series of ascending or descending voltage or current
changes called steps. The number of source steps is one less than the number of sourced points.
