Trigger.tsplinkin[N].Edge - Keithley 2450 Reference Manual

Model 2450 Interactive SourceMeter® Instrument Reference Manual
Details
The trigger event detector enters the detected state when an event is detected. When this command is sent, the
instrument does the following actions:
• Clears the trigger event detector
• Discards the history of the trigger line
• Clears the trigger.tsplinkin[N].overrun attribute
Example
tsplink.line[2].mode = tsplink.MODE_TRIGGER_OPEN_DRAIN
trigger.tsplinkin[2].clear()

trigger.tsplinkin[N].overrun
tsplink.line[N].mode

trigger.tsplinkin[N].edge

This attribute indicates which trigger edge controls the trigger event detector for a trigger line.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
detectedEdge = trigger.tsplinkin[N].edge
trigger.tsplinkin[N].edge = detectedEdge
detectedEdge
N
Details
When the edge is detected, the instrument asserts a TTL-low pulse for the output.
The output state of the I/O line is controlled by the trigger logic, and the user-specified output state of the line is
ignored.
Example
tsplink.line[3].mode = tsplink.MODE_TRIGGER_OPEN_DRAIN
trigger.tsplinkin[3].edge = trigger.EDGE_RISING
