Usage
:TRIGger:BLOCk:WAIT <blockNumber>, <event>
:TRIGger:BLOCk:WAIT <blockNumber>, <event>, <logic>, <event>
:TRIGger:BLOCk:WAIT <blockNumber>, <event>, <logic>, <event>, <event>
<blockNumber>
The sequence of the block in the trigger model
<event>
The event that must occur before the trigger block will act
<logic>
If each event must occur before the trigger model continues:
AND
If at least one of the events must occur before the trigger model continues:
OR
Details
You can use the wait block to synchronize measurements with other instruments and devices.
Events that you can set the instrument to wait for include:
•
Digital input/output signals, such as DB-9 and TSP-Link
•
LAN events
•
Blenders
The event can occur before the trigger model reaches the wait block. If the event occurs after the trigger model
starts but before the trigger model reaches the wait block, the trigger model records the event. When the trigger
model reaches the wait block, it executes the wait block without waiting for the event to happen again.
The instrument clears the memory of the recorded event when the trigger model is at the start block and when
the trigger model exits the wait block.
You can have up to eight wait blocks in a trigger model.
All items in the list are subject to the same action — you cannot combine
AND
and
OR
logic in a single command.
The events can be one of the events shown in the following table.
