Deferred Commands Execution Order
The immediate commands take effect immediately when they are interpreted. Even so, they must be
followed by an
Execute (
X
) command to terminate the command string for correct operation. For
example, the Enter Calibration Mode (
K
) command
K00001X
.
Deferred commands are not executed until the Execute (
X
) command has been successfully parsed and
interpreted. Upon interpretation of the Execute (
X
) command, the order of execution of all deferred
commands is as shown in the table.
This ordering ensures that the configuration of acquisitions takes place before any data is acquired.
The
Set Trigger Configuration (
T
) command is the last command performed before the issuance of any
Trigger (trigger start event) since data acquisition may begin once the
T
command has been defined.
