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.
