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.
