Models 2510 and 2510-AT User’s Manual Common Commands 8-5
*WAI — wait-to-continue Wait until previous commands are completed
Effectively, the *WAI command is a No-Op (no operation) for the Model 2510 and thus,
does not need to be used.
Two types of device commands exist:
• Sequential commands — A command whose operations are allowed to finish
before the next command is executed.
• Overlapped commands — A command that allows the execution of subsequent
commands while device operations of the Overlapped command are still in
progress.
The *WAI command is used to suspend the execution of subsequent commands until the
device operations of all previous Overlapped commands are finished. The *WAI command
is not needed for Sequential commands.
