Inside the Idle State
Turning power on, or sending
*RST
or

forces the trigger
system to the idle state. The trigger system remains in the
idle state until it is initiated by
1NITiate:IMMediate
or
INITiate:
CONTinuous
ON . Once one of these conditions is satisfied,
the trigger system exits downward to the initiate state. Note that
*RST
sets
INITiate
:
CONTinuous
OFF.
Whenever the trigger system leaves the idle state, it sets the
instrument’s Operation Pending Flag. Returning to idle clears
the flag. The Operation Pending Flag is a special bit inside the
instrument that can affect how the instrument responds to certain
commands. You need to know this fact when using
*OPC,

*WAI,
and other commands.

Inside the Initiate State
If the trigger system is on a downward path, it travels directly
through the initiate state without restrictions. If the trigger system
is on an upward path, and
1NITiate:CONTinuous
is ON, it exits
downward to an event-detection state. If the trigger system is on an
