a specific signals, but i NEED ALL. i NEED TO ACQUIRE THESE SIGNALS FOR IMAGE ANALYSIS. I hope to get

reply soon.

Do you need to measure quality of the SIGNAL, or quality of the SCREEN?

[Yesh]

I need to measure the quality of the signal for now.

But I also may need measure quality of the display.

thanx for responding so quickly.

[Andrey_Dmitriev]

Then, I don't believe that you will found single device for measurement.

Probably something from tektronix or other vendor will help you.

The sites and hardware you sugested would it be compatible with labview

for image analysis.

Analogkid2DigitalMan, I have gone through the links you have sent me, but

the boards are sort of analysis tools and I am plannig to build our own image

applications using labview.

[AnalogKid2DigitalMan]

Yesh:

Very well. When I read you wanted to measure the quality of the video signal, the VideoMaster software analysis routines came to mind.

Yes, if you're looking to test the quality of the a video signal, the relevant product from NI is definitely VideoMaster (for the PCI system).
