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()
Clears the trigger event on TSP-
Link line 2.

trigger.tsplinkin[N].overrun (on page 8-340)
tsplink.line[N].mode (on page 8-348)
trigger.tsplinkin[N].edge
This attribute indicates which trigger edge controls the trigger event detector for a trigger line.

Configuration script trigger.EDGE_FALLING
Usage
detectedEdge = trigger.tsplinkin[ N ].edge
trigger.tsplinkin[ N ].edge = detectedEdge
detectedEdge The trigger mode:
•
Detect falling-edge triggers as inputs:
trigger.EDGE_FALLING
•
Detect rising-edge triggers as inputs:
trigger.EDGE_RISING
•
Detect either falling or rising-edge triggers as inputs:
trigger.EDGE_EITHER
N The trigger line (1 to 3)
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. 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
Sets synchronization line 3 to
detect rising edge triggers as input.
