Details
This attribute controls the mode in which the trigger event detector and the output trigger generator operate on
the given trigger line.
The setting for

Description
tsplink.TRIG_BYPASS 0 Allows direct control of the line as a digital I/O line.
tsplink.TRIG_FALLING 1 Detects falling-edge triggers as input. Asserts a TTL-low pulse
for output.
tsplink.TRIG_RISING 2 If the programmed state of the line is high, the
tsplink.TRIG_RISING
mode behaves similarly to
tsplink.TRIG_RISINGA
.
If the programmed state of the line is low, the
tsplink.TRIG_RISING
mode behaves similarly to
tsplink.TRIG_RISINGM
.
Use
tsplink.TRIG_RISINGA
if the line is in the high output
state.
Use
tsplink.TRIG_RISINGM
if the line is in the low output
state.
tsplink.TRIG_EITHER 3 Detects rising- or falling-edge triggers as input. Asserts a
TTL-low pulse for output.
tsplink.TRIG_SYNCHRONOUSA 4 Detects the falling-edge input triggers and automatically
latches and drives the trigger line low.
tsplink.TRIG_SYNCHRONOUS 5 Detects the falling-edge input triggers and automatically
latches and drives the trigger line low. Asserts a TTL-low pulse
as an output trigger.
tsplink.TRIG_SYNCHRONOUSM 6 Detects rising-edge triggers as an input. Asserts a TTL-low
pulse for output.
tsplink.TRIG_RISINGA 7 Detects rising-edge triggers as input. Asserts a TTL-low pulse
for output.
tsplink.TRIG_RISINGM 8 Edge detection as an input is not available. Generates a
TTL-high pulse as an output trigger.
