trigger functions
The functions in this group are used to control triggering.
Example Resets the timer and then measures the time since the reset:
timer.reset()
...
time = timer.measure.t()
print(time)
Output: 1.469077e+01
The above output indicates that timer.measure.t was executed 14.69077 seconds
after
timer.reset.
timer.reset
Function Resets the timer to 0 seconds.
Usage timer.reset()
Remarks This function will restart the timer at zero.

trigger.clear
Function Clears the command interface trigger event detector.
Usage trigger.clear()
Remarks
The trigger event detector remembers if an event has been detected since the last
trigger.wait call. This function clears the trigger’s event detector and discards the
previous history of command interface trigger events.
Details See “Triggering” in Section 10.
Also see trigger.wait
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.
