The CompuVideo scope is a PIECE OF CRAP, it is worse than the Hamlet HD scope that I badmouthed in my post on this subject. CompuVideo is a guy from Brooklyn that used to fix VTR’s in NY. He found some Asian company that makes cheap Oscilloscopes, and modifies them so they can act as a waveform monitor. As the years went on, he kept making new input boards (probably sourcing them) to convert SDI and HD-SDI to composite to display the signal on the Oscilloscope. If any of you have ever had any electronics courses, you may have seen what an oscilloscope looks like – with lots of knobs for vertical amplitide, horizontal timebase, trigger controls, etc. ALL OF THESE USELESS AND CONFUSING controls are on all the CompuVideo products – because they are OSCILLOSCOPES – not dedicated waveform monitor/vectorscopes.
If I had a gun held to my head, and I had to choose between the Astro Systems, Hamlet and CompuVideo, (all terrible products), I would choose the Astro Systems or Hamlet in a HEARTBEAT before the CompuVideo scope for professional video applications.
Again, professional scopes come from Leader, Tektronix, Videotek, (and built into the Panasonic LCD BT-LH series), and functional but not great scopes come from Hamlet and Astro Systems, but the CompuVideo product is an oscilloscope, not a waveform monitor – no matter what their product info says. You can get any Tektronix oscilloscope to show a waveform display – put an AJA HD-SDI to composite converter in front of it, and it will show an HD waveform signal.
