The trigger mode
N
The trigger line (1 to 3)
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
mode
can be one of the following values:
Mode Number
value 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.
