The question is a bit vague, so I'll waffle.  Version 3b1 and 3c1
provide arbitrary sources that are undocumented and much more powerful
than the arbitrary sources in 2g6.  If you don't mind C coding, you
can add devices reasonably easily to the above two versions (speaking
from experience).  There's documentation that describes how to add new
devices in the Programmer's Manual.
