Event blenders
The ability to combine trigger events that occur at different times is known as event blending. An
event blender can be used to wait for a specific input trigger or to wait for up to four input triggers to
occur before responding with an output event.
There are 1 or 2 event blenders that you can use to monitor and respond to multiple stimulus events.
Each event blender can be configured to monitor a maximum of four different trigger events.
Event blender operations
You can use event blenders to perform logical AND or logical OR operations on trigger events. For
example, trigger events can be triggered when either a manual trigger or external input trigger is
detected.
When AND operation is selected, the event blender generates an event when an event is detected on
all of the assigned stimulus inputs.
When OR operation is selected, the event blender generates an event when an event is detected on
any one of the four stimulus inputs.
You set the event blender operation using remote commands.
Using SCPI commands:
Send the command :TRIGger:BLENder<n>:MODE.
Set the command to OR or AND.
Using TSP commands:
Send the command trigger.blender[N].orenable.
Setting the command to true enables OR operation; setting it to false enables AND operation.
Assigning blender trigger events
Each event blender has four stimulus inputs. You can assign a different trigger event to each stimulus
input.
You set the event trigger events operation using remote commands. See the command descriptions
for the list of events that you can assign.
Using SCPI commands:
Send the command :TRIGger:BLENder<n>:STIMulus<m>.
Using TSP commands:
Send the command trigger.blender[N].orenable.
Trigger blender action overruns
The event blenders can generate action overruns.
When the event blender operation is set to AND, overruns occur when a second event on any of its
inputs is detected before an output event is generated.
When the operation is set to OR, overruns occur when two events are detected simultaneously.
Use the status model to monitor for the occurrence of action overruns (for details, see the
Status
model (on page C-1)).
