    I have an old function generator that I want to repair for work and I cannot seem to find any information about it. I do not even have the name of the manufacturer. I figured I would ask on here to see if anyone can help.

    The model is "Model 339 Digital Ramp/Step Function Generator" but I can find no company name anywhere on it. If I can figure out the company that made it I might be able to contact them to get some info and prints.

    I have attached a picture of the front and back. If anybody recognizes it or has some insight into who might have made this please let me know! Thanks!
