Hello everyone, long time lurker first time poster. A friend was recently able to dig up an old vectorscope (oscilloscope?), the Compuvideo SVR-1100S8B, and I am having trouble finding any information on it. I can't seem to find any manuals or user/service guide, so I am maybe thinking that this is just a rebrand of another scope. I'd like to have some sort of information since I would like to repair it, since it just displays a singular dot, which can be moved around with the pan.
Does anyone have any info or manuals, or know what scope it is based on?
