Chrominance Phase Measurement

[NormanSim]

Measure the chrominance phase of RGB color. Now I using Video analyzer to measure and would like to replace using NI.

RGB colour strictly speaking does not have chrominance, therefore you cannot measure RGB chrominance phase. Only PAL and NTSC Composite (CVBS and S-Video formats) video has chrominance.
To make this and many other detailed analogue video measurements you should consider VideoMASTER from microLEX Systems in Denmark - a National Instruments Alliance member. Their VideoMASTER product uses the NI 5122 digitiser card to acquire video signals and analyse them with their own special software.

It sounds like you are trying to analyze the video signal rather than acquire and analyze an image. If this is the case, you might consider re-posting this question under the Measurement Hardware category (perhaps in the High-Speed Digitizer or Multifunction DAQ sub-categories). I would also recommend contacting a Technical Sales Representative, at 1-888-280-7645, for assistance configuring a system specific to your needs.

I've seen the VideoMASTER of mocroLEX. It's really a successful solution of video analyzer. But I do not need all functions provided in mocroLEX's software package. The only one question to me now is to figure out how to measure the chroma phase by NI 5122. Does anyont know how to calculate it from a video line waveform (any mathematic equation) of a function to do it ?
