Really nice toys!
The top one looks like a modular thingie, with changeable modules?
It is, it's a 6 slot mainframe (I think that's what they call it). There are 2 doubles and 2 singles in it.
It needs a fan, but I have one ordered, and the programmable power supply will want calibrating, but for what I'm using it for, the 3456A will do for calibrating it.
I also got a precision bench source. It looks like it's controlled from a PC, as there are no settings on it, but it has a USB connection and an ethernet connection. I've plugged it into the PC, and it enumerates as a 'TTG-001 DC source', but no drivers are found. I can't find anything on the internet about it, and there is no manufacturer's name on or in the box, so I'm guessing it's a proprietary bit of kit for something.
I used Wireshark to try to determine its IP address but it's not being broadcast, so unless I can find how to control it, it looks like I'll end up robbing it for the power supply board and binning the sexy looking control board.
If anyone knows anything about it...?
