NI PXI-5421 function generator

[Ravikumar.C]

is it possible to generate Component Video signals , R, G,B video signals using NI PXI-5421?

I need R, G, B and X and Y video signals as input to Test video processing boards.

Hi Ravikumar.C, 

As in for creating Custom Composite RGB Video patterns, the 5431 was used, but it was declared enf-of-life back in 2007. With that card you had the possibility to create R, G and B signals separetly and download them into three NI- 5431s (one per signal) as you can see in the following link:

Create Custom Composite, Y/C, and RGB Video Test Patterns

 Its predecessor is the 5421 uses the NI Analog Video Generator, which is a comprehensive tool for generation of video signals for analog video, primarily Composite Video (CVBS), and S-Video. It offers several ways to create and generate standardized as well as arbitrary, analog composite video signals. The Video Modes for this are composite signal on a single channel or 2 channel S-Video format with Y and C signals, and  formats as  M-NTSC, Standard PAL, M-PAL, N-PAL, NC-PAL, SECAM, NTSC-2, NTSC 4.43, STANAG or RS-343-A, but no RGB composite.

You can check more information about the NI Analog Video Generator by going to its User Manual:

Thanks for information, another question is there any PXI instruments which able to genereate component video signals?

Hi Ravikumar.C, 

I was not able to find a PXI card that would generate the three separete RGB signals with just one card.

I was able to find this example, is this something similar to what you want to do?

RGB Video Generation Using the NI 5431 Video Generator

According to that you could be able to do it with 3 separete syncronize cards. Also you could use the Analog Video Generator Software.
