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
, initiation needs to be satisfied to take the instrument 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:
•
:ABORt
•
*RCL 0
•
:SYSTem:PREset
•
*RST
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 initiation.
Therefore, operation will immediately leave the idle state when it is sent. The *RCL 0 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:
•
:INITiate
•
:INITiate:CONTinuous ON
NOTES
While in remote, pressing the LOCAL key restores continuous front panel operation.
When switching from the 182 language to the SCPI language, the instrument will go
into the idle state and stay there. You can take the instrument out of idle by pressing
the TRIG key or by sending an initiate command.
