Syntax
∗WAI
Function
The unit goes into waiting state until the operation of the previous command has been
completed.
Note
The ∗WAI command is accepted by the 9518-02 interface because it is a standard command as
specified by IEEE-488.2 1987. However, since all of the commands specific to the 3157 are in
any case sequential commands, using this *WAI command never has any effect.
Example
Waits until all execution is fully completed.
Transmission ∗WAI

If the data parameters are set after this command, a command error occurs.
