When measuring RED,GREEN,BLUE video analog signals with a oscilloscope all i see is noise and fuzzy waveforms under 1 volt is this right? When measure RED,GREEN,BLUE video analog signals with a oscilloscope what am i actually seeing? this isn't a true measurement right cause its a oscilloscope and not a video waveform monitor But i read that when troubleshooting video gear or TV's you CAN NOT. I have not yet persuaded myself it is worth. 50W audio amplifers.
