6.6.8 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.

6.6.9 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: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.
Note: You cannot initiate measurement triggers continuously. Otherwise, the
measurement data in the data buffer would continuously be
overwritten by each triggered measurement.
