Chapter Three

Control Reference

Auto: After a timeout, if a real hardware trigger is not received, then force a trigger so there are
automatically lots of updates.

Normal: Accepts triggers as rapidly as the system permits, but likewise will wait "forever" for a trigger,
without updating anything.

Single: Arm the acquisition system to acquire once, and do not rearm automatically after. Once a
trigger is received and the data processed, the instrument finishes in the "Stopped" state.

Stop: Finishes the current acquisition and does not re-arm.

' Visual Basic Script
Set app = CreateObject("LeCroy.XStreamDSO")

' Place the instrument in stopped mode and take one acquisition.
app.Acquisition.TriggerMode = "Stopped"
app.Acquisition.Acquire(5)
