Usage
triggered

: A trigger was detected during the timeout period
false

timeout
Maximum amount of time in seconds to wait for the trigger
Details
This function waits up to
timeout
seconds for a trigger on the active command interface. A command interface
trigger occurs when:
•
A GPIB GET command is detected (GPIB only)
•
A VXI-11 device_trigger method is invoked (VXI-11 only)
•
A *TRG message is received
If one or more of these trigger events were previously detected, this function returns immediately.
After waiting for a trigger with this function, the event detector is automatically reset and rearmed. This is true
regardless of the number of events detected.
Example
triggered = trigger.wait(10)
print(triggered)
Waits up to 10 seconds for a trigger.
If
false
is returned, no trigger was detected
during the 10-second timeout.
If
true
is returned, a trigger was detected.
