Trigger model (remote operation)

The following paragraphs describe how the Model 2790 operates for remote operation.

the trigger model because operation is controlled by SCPI commands from the Trigger
subsystem. Key SCPI commands are included in the trigger model.
Idle and initiate
The instrument is considered to be in the idle state whenever operation is at the top of the
trigger model. As shown in
ment out of idle. While in the idle state, the instrument cannot perform any measure or
step/scan operations.
The following commands will return operation to the top of the trigger model (idle) at the
START point of the trigger model:
•
•
•
•
What happens next depends on the state of initiation. If continuous initiation is already
enabled, the instrument will leave the idle state. SYSTem:PRESet enables continuous ini-
tiation. Therefore, operation will immediately leave the idle state when it is sent. The
*RCL command will do the same if INITiation:CONTinuous ON is a user-saved default.
*RST disables continuous initiation. Therefore, the instrument will remain in the idle
state.
Either of the following two initiate commands will take the instrument out of the idle state:
