digio.trigger[N].mode
This attribute sets the mode in which the trigger event detector and the output trigger generator operate on the
given trigger line.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
triggerMode = digio.trigger[N].mode
digio.trigger[N].mode = triggerMode

N
Details
Set triggerMode to one of the following values:
Trigger mode values
triggerMode
digio.TRIG_BYPASS or 0
digio.TRIG_FALLING or 1
digio.TRIG_RISING or 2
digio.TRIG_EITHER or 3
digio.TRIG_SYNCHRONOUSA or 4
digio.TRIG_SYNCHRONOUS or 5
digio.TRIG_SYNCHRONOUSM or 6
digio.TRIG_RISINGA or 7
digio.TRIG_RISINGM or 8
When programmed to any mode except digio.TRIG_BYPASS, 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.
Use of either digio.TRIG_SYNCHRONOUSA or digio.TRIG_SYNCHRONOUSM is preferred over
digio.TRIG_SYNCHRONOUS, because digio.TRIG_SYNCHRONOUS is provided for compatibility
with the digital I/O and TSP-Link triggering on older firmware.

Description
Allows direct control of the line.
Detects falling-edge triggers as input; asserts a TTL-low pulse
for output.
If the programmed state of the line is high, the
digio.TRIG_RISING mode behavior is similar to
digio.TRIG_RISINGA. If the programmed state of the line is
low, the digio.TRIG_RISING mode behavior is similar to
digio.TRIG_RISINGM. Only use this setting if necessary for
compatibility with other Keithley Instruments products.
Detects rising- or falling-edge triggers as input. Asserts a
TTL-low pulse for output.
Detects the falling-edge input triggers and automatically
latches and drives the trigger line low. Asserting the output
trigger releases the latched line.
Detects the falling-edge input triggers and automatically
latches and drives the trigger line low. Asserts a TTL-low
pulse as an output trigger.
Detects rising-edge triggers as input. Asserts a TTL-low pulse
for output.
Detects rising-edge triggers as input. Asserts a TTL-low pulse
for output.
Asserts a TTL-high pulse for output. Input edge detection is
not possible in this mode.
