    How do you troubleshoot color correction boxes?

    You can't use a function generator , so what do you use to inject into the color inputs?

    NTSC, PAL, SECAM signals

    How do you Display the color waveforms on the o-scope?

    Because using a O-scope you can't view or display the color signal waveforms, why is that?

    what is the generator called that outputs color frequencies for NTSC, PAL, SECAM?

    Are they called color frequency generators or they use something else?

    But do you put the NTSC, PAL, SECAM signals into the O-scope external trigger , so you can view/display the Color frequency waveforms?

    NTSC, PAL, SECAM signals are a timing signal? or what kind of signals are they?
