Details
This attribute selects which events cause the arm event detector to enter the detected state.
Set this attribute to 0 to start the scan without waiting for an event. eventID may be one of the following trigger
event IDs:
•
digio.trigger[N].EVENT_ID: An edge (either rising, falling, or either based on the configuration of
the line) on the digital input line
•
display.trigger.EVENT_ID: The trigger key on the front panel is pressed
•
trigger.EVENT_ID: A *trg message on the active command interface. If GPIB is the active command
interface, a GET message will also generate this event
•
trigger.blender[N].EVENT_ID: A combination of configured events has occurred
•
trigger.timer[N].EVENT_ID: A delay expired
•
tsplink.trigger[N].EVENT_ID: An edge (either rising, falling, or either based on the configuration
of the line) on the tsplink trigger line
•
lan.trigger[N].EVENT_ID: Event identifier use to route the LAN trigger to other subsystems
(using stimulus properties)
•
scan.trigger.EVENT_SCAN_READY: Scan Ready Event.
•
scan.trigger.EVENT_SCAN_START: Scan Start Event
•
scan.trigger.EVENT_CHANNEL_READY: Channel Ready Event
•
scan.trigger.EVENT_SCAN_COMP: Scan Complete Event
•
scan.trigger.EVENT_IDLE: Idle Event
Use one of the text trigger event IDs (for example, digio.trigger[N].EVENT_ID) to set the
stimulus value rather than the numeric value. Doing this will make the code compatible for future
upgrades.
Example 1
scan.trigger.arm.stimulus =
scan.trigger.EVENT_SCAN_READY
Example 2
scan.trigger.arm.stimulus = 0
Example 3
scan.trigger.arm.stimulus = digio.trigger[3].EVENT_ID The scan begins when the
