Details
There are two types of device commands:
• Overlapped commands: Commands that allow the execution of subsequent commands while
instrument operations of the overlapped command are still in progress.
• Sequential commands: Commands whose operations must finish before the next command is
executed.
The *WAI command suspends the execution of commands until the instrument operations of all previous
overlapped commands are finished. The *WAI command is not needed for sequential commands.
