Keithley 2000 - Trigger model (GPIB operation)

Trigger model (GPIB operation)
This section describes how the Model 2000 Multimeter operates over the GPIB bus. The
flowchart in Figure 4-11 summarizes operation over the bus and is called the trigger model. It is
called the trigger model because operation is controlled by SCPI commands from the Trigger
subsystem (see Section 5 for more information). Key SCPI commands are included in the trigger
model.
