trigger.timer[N].stimulus
Remarks
This attribute selects which event will start the timer.
eventid may be one of the following (existing 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 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
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_MEASURE_COMP: Measure Complete Event
scan.trigger.EVENT_SEQUENCE_COMP: Sequence Complete Event
scan.trigger.EVENT_SCAN_COMP: Scan Complete Event
scan.trigger.EVENT_IDLE: Idle Event
NOTE Use the ICL define to set the stimulus value rather than the define value.
Doing this will make the code compatible for future upgrades because it
may need to change when enhancements are added to the instrument.
Example
To print the delay:
print(trigger.timer[1].stimulus)
trigger.timer[N].wait()
Function
Wait for a trigger.
Usage
triggered = trigger.timer[N].wait(timeout)
N: is a trigger timer value (from 1–4).
timeout: Maximum amount of time in seconds to wait for the trigger.
triggered: Trigger detection indication.
Remarks
This function will wait for a timer trigger. If one or more trigger events were detected
since the last time trigger.timer[N].wait or trigger.timer[N].clear (on page 13-290) was
called, this function will return immediately.
After waiting for a trigger with this function, the event detector will be automatically
reset and rearmed. This is true regardless of the number of events detected.
