Programming

*WAI (Wait)

The *WAI command prevents the instrument from executing any further com-

mands until the current command has finished executing. All pending opera-

tions are completed during the wait period.

Usage:

GPIB only

Command Syntax:

*WAI

Example: OUTPUT 711;":ROUTE:LAYER1:CHANNEL A2,B4"

OUTPUT 711;"*WAI"

OUTPUT 711;"SYSTEM:CONFIG?"

ENTER 711;DUMMY$

NOTE

The *WAI command can be used to ensure all switch movement operations have com-

pleted before continuing the program. Following a ROUTE:LAYER:CHANNEL command

with a *WAI command followed by a query, will ensure the query is not answered until

the switch has settled to its new position.
