Can the PXI 5431 produce a differential NTSC signal

[rfoidjsfjsdfjoiasdja]

I have a 5431 sig generator, can i use it to produce NTSC differential signal, is it hard to load images onto the card for outputting.

Dear Derek,

I hope you are doing fine and thank you for contacting National Instruments. You can generate an NTSC waveform with PXI 5431. Here is the data sheet for the PXI 54341.

Also can you be more specific what you are doing in your application and what hardware have you got. Please click  here to find example programs for generating video data with PXI 5431.

I hope this helps.

Best regards,

Fawad,

Thanks for the reply.

To be more specific, this is what i am trying to do.

I have an electronics unit which takes in an NTSC differential signal, processes it and and outputs it as a single ended NTSC output.

The unit also takes an LVDS signal on other ports which I am not interested in testing.

I want to test the unit in high volume production by generating this differential signal and inputting it to the Electronics unit with 100 ohm input impedance, turning on this port and testing the NTSC signal on the output.

Also, i have a specific bitmap which i would like to use to test, can i load this to the generator and output it continuously.

Hope this sheds more light on the application i am looking to use the 5431 for

Regards,

Derek

Dear Darek,

I hope you are doing fine. Thank you for your reply. To answer your question. The 5431 ships with software for converting digital bitmap images to analog video waveforms. Also you can program to create a new bitmap and converts it to the binary file and then loads the image on card and display. Please see the following forum post that might be of help to you.

Can you please explain what you mean by differential NTSC signal as device is capable of producing NTSC signal as mentioned in datasheet ?

Hi Derek,

Just a quick word of caution - the PXI-5431 is no longer available from NI.  If you're designing it into a test system, please be aware that it will be difficult to duplicate your system or find replacements.
