Thanks in advance. 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. -rich
