NOW has developed several generations of stimulus-generation equipment, for a test station used to test and develop printed circuit boards for an advanced military airborn/flight display systems. A system contains up to three boards of the same type, where each board has three video outputs, two analogue and one digital. The analogue outputs can be synchronized to an external sync signal. The boards are controlled via buttons on the front panel, or with commands from the control computer via GPIB, IEEE-488.2. The equipment simulates the video from cameras, IR-cameras, radar and so on, and delivers several outputs of different video standard.
