*WAI
Wait to continue
Syntax:
*WAI
Parameters:
None
Function:
The *WAI command causes the device to wait until all pending operations are
complete before processing any commands waiting in the input queue. Care
should be taken when using this command since it is possible to overflow the
input queue by continuing to write commands to the 2835-C while the *WAI
command is in effect.
Note that the *WAI command will essentially “lock out” the remote interfaces
until all pending operations are complete. The *OPC command and *OPC?
query differ from *WAI in this area, as they allow other commands to be
processed while they are waiting for pending operations to complete.
Once the *WAI command is received, it will be in effect while any of the
following operations are in progress:
Single acquisition in progress
Data store in progress with fixed data store buffer
The meter is ranging
The *WAI command can only be canceled by a GPIB interface device clear or
by turning the meter off and on.
