Type TSP-Link accessible
Affected by Where saved Default value

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 s for a trigger.
If false is returned, no trigger was detected
during the 10 s timeout.
If
true
is returned, a trigger was detected.
