How can I synchronize analog intputs and outputs using Data Acquisition Toolbox?

I am using Data Acquisition Toolbox and would like to synchronize an analog input and analog output object.

Synchronization of analog inputs and outputs can only be achieved through the use of hardware triggering. It is also possible to trigger two analog input objects at approximately the same time using software triggering, however they will not be synchronized.

If you wish to use hardware triggering, you will need to make sure that your hardware is capable of the type of synchronization you want to do. For example, some boards may have separate trigger pins for analog inputs and outputs. Please see the following page for a list of the hardware supported by Data Acquisition Toolbox:

The following example shows how to use analog input channels and analog output channels together with a single Session object running near simultaneous.
