    video signals on oscilloscope


    when measuring video signals on the oscilloscope the video waveforms don't look clear but interlaced,encoded,modulated signals why is that and how do i make them more clear?

    I measured VCA, RGB, component,composite, S video they all look very distorted,interlaced,encoded,modulated on the analog oscilloscope

    what am i doing wrong and how can i correct this?

    Sometimes the vertical sync will be on the RED channel and hortizontal will be on the blue channel why is that?

    The video waveforms look very hazy and blurry

    how do you guys set up your oscillscopes when measuring video signals?

    Why doesn't VCA and RGB has a colour burst? on composite has a colour burst why is that?

    Horizontal sync pulse is 5us , vertical is 400us?
