edit

I noticed that there is either link spam, or just a want for producers of Vectorscopes to be listed on this article. I gave it it's own section, and added the company "Hamlet" who were just appended to the end of the audio secion of the article. I also added Sony and Tektronics, to keep a fair varity of information on the subject open.

Although I would assume that there isn't a need for information on who makes vectorscopes, as if you need one you should already know who makes them.
