Thread: Vectorscope

  1. #1


    Hi all,
    This is probably a bit of a long shot on here, but does anyone know where I could get a circuit diagram and or repair information for my Electronic Visuals EV4020a vectorscope, it's quite old and out of calibration, but I've used it enough to know how "wrong" it is. Any help would be appreciated.

    What do you mean by "out of calibration"? Most scopes have calibration controls on their panels. Do you mean that it is drifting?

    Actually me saying it's out of cal. is a bit misleading, it's actually broke ! There is no display at all now, just a dot on the CRT. What I meant by out of cal was when I put known good 100% bars it looks like they are out but I know this and take account of it ! Its just my excuse for continuting to use such an old piece of kit...

    I'm a bit confused by what you are saying. Could you post a picture of the output it is generating?
