Section 3 Command Descriptions
3.10
Execute X
Commands sent to the Digital488 will result in no action until the unit is
instructed to execute these commands. This is done by sending an X, usually as the last
character of a command string. Commands sent without an X are stored in the internal
buffer until an X is received. Any number of Execute commands may be inserted into
the same command string. Certain commands, such as Bit Set require an X after each
command in a string if more than one of that command is within the same string.
Example:
CLEAR 718 reset the Digital488
OUTPUT 718;"F2" send "F2" to the Digital488 command
input buffer
OUTPUT 718;"X" instruct the Digital488 to execute its
command input buffer
OUTPUT 718;"A1XA2X" two Bit Set (A) commands are within the
same string, requiring an X after each
command.
