Trigger.tsplinkin[N].Edge - Keithley DMM7510 Reference Manual

Model DMM7510 7½ Digit Graphical Sampling Multimeter 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()
Also see
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. 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
