Actions Upon an Event
If an event occurs, the system provides the following options:
• Go to:
Go to a certain data block in the overall sequence and execute that
block. The block is identified by its block label. The implicit "End" block
(which is automatically assigned and needs not be defined) terminates
the sequence and hence the test.
• Trigger:
Launch a trigger pulse to the TRIGGER OUTPUT of the central clock
module.
• VXI-T01:
Set the VXI ECL trigger lines T0 and T1 to 01, 10, or 11.
All these options can be freely combined.
Summary of Event-Related Terms
Event:
A signal that must be responded to.
An event that causes an action at the end of the currently executed data
block.
An event that is serviced as fast as possible, without waiting for the end of
the currently executed data block.
Any combination of the following:
• Go to data block.
• Set the TRIGGER OUTPUT of the central clock module.
• Set the VXI ECL T0/T1 trigger lines.
