Trigger.tsplinkout[N].Logic - Keithley 2450 Reference Manual

Section 8: TSP command reference

trigger.tsplinkout[N].logic

This attribute defines the trigger output with output logic for a trigger line.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
logicType = trigger.tsplinkout[N].logic
trigger.tsplinkout[N].logic = logicType
logicType
N
Details
This attribute controls the logic that the output trigger generator uses on the given trigger line.
If the output logic is set to trigger.LOGIC_POSITIVE, the trigger generator asserts a TTL-high pulse for
output.
If the output logic is set to trigger.LOGIC_NEGATIVE, the trigger generator asserts a TTL-low pulse for
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.tsplinkout[3].logic = trigger.LOGIC_POSITIVE
