After reading a part of a topic about programming a Chinese AFG I was triggered to search info about programming mine and so I found this topic, to bad it turned out to be mine with no responses.
But regular looking for documentation you could not find in the past, is often useful because more and more doc gets online over time.
It is still going strong, it is a truly wonderful instrument with great performance but there is one big disadvantage with this kind of kit. Nobody seems to have problems with it so it is hard to find info on forums. That is the advantage of Chinese gear, they have so much problems that, after a while, they all are documented into great detail on forums.
