Details
There are two types of instrument 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. Typically, this command is sent after the initiate trigger model command.
