Idle
The instrument is considered to be in the idle state whenever it is not performing any measurement.
Wait for Trigger
The control source holds up operation until the programmable event occurs and is detected. See
description below for trigger sources:
 Immediate
With this trigger source, event detection happens immediately.
 External
Event detection happens when either of the following takes place:
