About the Model 494.45 8-Input A/D Card
The Model 494.45 8-Input A/D Card is a mezzanine card that you can plug
into one of the slots on the Model 494.40 I/O Carrier board. Each A/D card
accepts up to eight analog input signals that must be within ± 12.5 V DC.
The A/D card also includes a software-configurable digital filter for each
input.
External analog signals include stand-alone function generators, external
controller outputs, or a computer-controlled analog output. Analog input
signals are typically routed to the A/D card through a Model 494.75 8-Input
BNC Transition Board. The transition board connects to the front-panel
connectors on the I/O carrier board that contains the A/D card.
