Trigger System; System-Wide States And Transitions - Keysight E4980A User Manual

Overview of Remote Control

Trigger System

Trigger System
The trigger system is responsible for such tasks as detecting the start of a
measurement cycle (triggering) and controlling the system state. As
8-12
"Waiting for Trigger," or "Measurement."
Figure 8-12 Trigger system
The following subsections describe each state and explain how the trigger
system switches among the states.

System-wide states and transitions

"Idle" State
The trigger system switches to "Idle" state when one of the following
commands has been executed. In the "Idle" state. measurement data and
monitor data can be read with query commands of the :FETCh subsystem.
Also, turning on the power to the instrument puts the trigger system into "Idle"
state. When the power is turned on, however, the continuous initiation mode is
on and the trigger source is set to "Internal"; accordingly, the trigger system
immediately switches to the "Waiting for Trigger" state and subsequently
repeats transitions between the "Measurement" and "Waiting for Trigger"
states.

When the DC bias function is turned on, the trigger system switches to the
"Idle" state.
