trigger.clear()
Remarks
The trigger event detector remembers if an event has been detected since the last
trigger.wait() (on page 13-290) call. This function clears the trigger's event detector and
discards the previous history of command interface trigger events.

trigger.wait() (on page 13-290)
trigger.wait()
Function
Wait for a trigger event.
Usage
triggered = trigger.wait(timeout)
timeout: Maximum amount of time in seconds to wait for the trigger.
triggered: Returns true if a trigger was detected. Returns false if no triggers were
detected during the timeout period.
Remarks
This function will wait up to timeout seconds for a GPIB GET command or a *TRG
message on the GPIB interface if that is the active command interface or a *TRG
message on the command interface for all other interfaces. If one or more of these
trigger events were previously detected, 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.
Also see
trigger.clear() (on page 13-289)
Example
Waits up to 10 seconds for a trigger:
triggered = trigger.wait(10)
print(triggered)
Output: false
The above output indicates that no trigger was detected during the 10 second timeout.
