Common Trigger
Configurations
In the previous paragraphs, you learned about the basic building
blocks allowed in a SCPI trigger system. Generally, an instrument
implements only a portion of the trigger features available. These
paragraphs discuss the simplest configurations:
INIT
and TRIG.
The INIT Configuration
The
INIT
configuration is the simplest possible trigger configuration.
It uses no event detection states, and requires only two subsystems
for programming,
INITiate
and
ABORt.
All SCPI instruments
implement these two subsystems.

Example commands using the
INIT
trigger configuration:
:
ABORt
abort operations, go to idle
:INIT:IMM execute one sequence operation
:INIT:CONT ON
execute sequence operations continuously
:
INIT:
CONT OFF
stop sequence operations after the current one is
complete
