Composite Black Burst???
 

Colin, using a BM intensity shuttle with your Scopebox - composite input - I see no burst in the waveform. Is this a Scopebox thing or a Intensity Shuttle thing? I ran into a situation where I needed to evaluate a house sync signal, i.e. BBurst. (Including the little burst on the front porch). Don't know if it can be done without using an old, analog Tektronix or Leader WF Monitor. Any ideas? Thoughts? Resign ourselves to a digital age...

ScopeBox can only see the in-raster data (that's all the capture devices pass), so things like that aren't going to be visible. In general, they don't exist in a digital signal at all. Are you monitoring an actual analog signal coming down something like a composite cable? Some digital scopes synthesize it, but at that point it loses most of the usefulness.

Yeah, I kinda figured that was the way it goes. Was working with an HD/SDI flypack that used BlackBurst, (i.e.composite video/burst sync with just 7.5 video black) as the 'house sync'. It's a 'rental', and some people used the 'tri-level sync' option instead, square waves that can fry the analog based dist. amps that send the house sync to all the gear in and external to the pack. Some gear wasn't seeing sync so we wanted to see if the signal had been corrupted by fried DA's. (More detail than wanted? ;-)
