Example 2
scan.trigger.arm.stimulus =
digio.trigger[3].EVENT_ID
Uses a trigger event on digital I/O
trigger line 3 to be the stimulus for
starting a scan.

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.

Description
digio.TRIG_BYPASS
or
0
Allows direct control of the line.
digio.TRIG_FALLING
or
1
Detects falling-edge triggers as input; asserts a TTL-low
pulse for output.
digio.TRIG_RISING
or
2
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
. This setting should only be used
if necessary for compatibility with other Keithley Instruments
products.
digio.TRIG_EITHER
or
3
Detects rising- or falling-edge triggers as input. Asserts a
TTL-low pulse for output.
digio.TRIG_SYNCHRONOUSA
or
4
Detects the falling-edge input triggers and automatically
latches and drives the trigger line low. Asserting the output
trigger releases the latched line.
digio.TRIG_SYNCHRONOUS
or
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.
digio.TRIG_SYNCHRONOUSM
or
6
Detects rising-edge triggers as input. Asserts a TTL-low
pulse for output.
