Here is a "basic setup" cheat-sheet I created for CompuVideo's SVR-1100CB vectorscope. Hopefully this will prove useful for other folks and avoid wasted time trying to figure out the right combinations of settings to operate it.
The manual does not appear to be available online (anyone here seen it?). The cheat-sheet is based off of original ones created back-in-the-day for somewhat similar models (below example is one from an eBay listing). Additional settings added to improve clarity.
