smuX.trigger.source
smuX.trigger.PULSE_COMPLETE_EVENT_ID
X = SMU channel (a or b)
Attribute
The pulse complete event number.
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
event_id = smuX.trigger.PULSE_COMPLETE_EVENT_ID
event_id
Pulse complete event number.
Remarks
• Set the stimulus of any trigger event detector to the value of this constant to have it respond to
pulse complete events from this SMU.
smuX.trigger.source.action
X = SMU channel (a or b)
Attribute
Sweep source action enable.
Default
smuX.DISABLE
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
action = smuX.trigger.source.action
-- Reads sweep source action.
smuX.trigger.source.action = action
-- Writes sweep source action.
action
Sweep source action.
Remarks
• This attribute is used to enable or disable source level changes during a sweep.
action
can be
set to one of the following values:
smuX.DISABLE
: Do not sweep the source.
smuX.ENABLE
: Sweep the source.
smuX.trigger.source.limitY
X = SMU channel (a or b)
Y = SMU measure function (i or v)
Where:
v
= voltage,
i
= current
Attribute
Sets the sweep source limit.
Default
limit
i
smuX.LIMIT_AUTO
limit
v
smuX.LIMIT_AUTO
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage
limit = smuX.trigger.source.limiti
-- Reads current source limit.
limit = smuX.trigger.source.limitv
-- Reads voltage source limit.
smuX.trigger.source.limiti = limit
-- Writes current source limit.
smuX.trigger.source.limitv = limit
-- Writes voltage source limit.
limit
Source limit during triggered operation.
Remarks
• Use this attribute to perform extended operating area (EOA) pulse mode sweeps.
• If this attribute is set to
smuX.LIMIT_AUTO
, the SMU will use the normal limit setting during
sweeping. If this attribute is set to any other value, the SMU will switch in this limit at the start of
the source action and will switch back to the normal limit setting at the end of the end pulse
action.
• 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.
