NI PXI/PCI-5431
System Block Diagram

The NI PXI/PCI-5431 composite video generator is a modified version of the NI 5411 arbitrary waveform generator and is an arbitrary waveform generator that replays downloaded video data. You can easily create the necessary video data by using the NI Video Software Toolkit that takes care of the needed calculations and driver functions especially developed to interface between the computer and the NI 5431.

In the following figure, the user interface is the NI Video Generator Wizard or LabVIEW software applications. You can use either application to generate video signals. The hardware driver is the NI-FGEN software, which sets up the NI 5431 that replays downloaded video data. The Compute Video Data occurs when the video generation software program, NI-VIDEO, is called to compute the data to be downloaded to the NI 5431. The Disk Save/Load represents the computer, which stores saved files generated from the User Interface and loads saved files to the NI 5431 and then generates the analog video signal on the Analog Video Output Connector.
