trigger.tsplinkout[N].logic
This attribute defines the trigger output with output logic for a trigger line.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Restore configuration
Instrument reset
Power cycle
TSP-Link line
N reset
Configuration script trigger.LOGIC_NEGATIVE
Usage
logicType = trigger.tsplinkout[ N ].logic
trigger.tsplinkout[ N ].logic = logicType
logicType The output logic of the trigger generator:
•
Assert a TTL-high pulse for output:
trigger.LOGIC_POSITIVE
•
Assert a TTL-low pulse for output:
trigger.LOGIC_NEGATIVE
N The trigger line (1 to 3)
Details
This attribute controls the logic that the output trigger generator uses on the given trigger line.
The output state of the digital 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.tsplinkout[3].logic = trigger.LOGIC_POSITIVE
Sets the trigger logic for
synchronization line 3 to output a
positive pulse.

trigger.tsplinkout[N].pulsewidth
This attribute sets the length of time that the trigger line is asserted for output triggers.
