Description of Triggering in Sweepers

The sweepers follow the SCPI model of triggering. It is a layered model with
the structure shown in F'igure 1-14.
I
The process of sweeping involves all three of these states. The IDLE state is
where the sweep begins. The IDLE state is left when the sweep is initiated.
This can happen on a continuous basis (INIT : CONT ON) or on a demand basis
by this command. When the INIT: CONT ON command is given, the sweep is
continuously re-initiated. When in the OFF state, the sweep is initiated with
the INIT : IMMediat e command.
