Inside the Sequence Operation State.
Figure

illustrates the
operation of the sequence operation state.
The downward entrance to the Sequence Operation State signals
that some instrument dependent action should begin at once. An
upward exit is not allowed until the instrument signals that its
action is complete. Note that complete can be defined differently for
different instruments. For example, consider an instrument that can
sweep a range of frequencies starting with and ending with
The
action-complete signal can be defined to coincide with the output of
either or
