The Model 706 is an IEEE-488 bus compatible scanner that can accommodate ten plug-in scanner cards. With ten scanner cards installed up to 100 2-pole channels can be on the same IEEE address. Using four additional Model 706s in a daisy chain configuration up to 500 2-pole channels can be on the same IEEE address. The Scanner adheres to standard IEEE-488 interface bus protocol. This enables the Model 706 to be incorporated into any measurement that uses programmed control through the IEEE-488 bus.
