6.8.7 SCPI Measurement Triggering Nomenclature
As previously explained under "Triggering Output Changes", the AC source uses the following
sequence name and alias for the measurement trigger system. This alias can be used instead of
the sequence form.
Sequence Form Alias
SEQuence3 ACQuire
6.8.8 Measurement Trigger System Model
Figure 6-3 is a model of the measurement trigger system. The rectangular boxes represent
states. The arrows show the transitions between states. These are labeled with the input or event
that causes the transition to occur.

6.8.9 Initiating the Measurement Trigger System
When the AC source is turned on, the trigger system is in the idle state. In this state, the trigger
system ignores all triggers. Sending the following commands at any time returns the trigger
system to the Idle state:
ABORt *RST *RCL
The INITiate commands move the trigger system from the Idle state to the Initiated state. This
enables the AC source to receive triggers. To initiate for a measurement trigger, use:
INITiate:IMMediate:SEQuence3 or
INITiate:IMMediate:NAME ACQuire
After a trigger is received and the data acquisition completes, the trigger system will return to the
Idle state. Thus it will be necessary to initiate the system each time a triggered acquisition is
desired.
