I bought a USB connected logic analyzer for too much money (not that
much). When buying, I did a mistake and not thought through the

needs to be a 220V country. As a result, I got an external power
supply that is 110V, which outputs 12V AC at 1000mA (why they do not
write "1A", I do not know).
To my shame, I actually bought a universal DC supply without
noticing that it's AC I need, and started a support call with the
company. They were very nice, and when we, finally, found out the
source (I hope it is it), the guy said I could probably get by with
18VDC, but it would strain the capacitors (my math suggests that
15VDC is closer to the mark).
So, does anyone know where I can get a 12V AC power supply? They are
not exactly a commodity.
You can buy a 230-> 120 volt transformer at home center. They are
around 100 NIS. Don't buy the 35 NIS ones, they will cause you trouble.
If you have a BEZEQ Siemens router (some say Rotal on them) it uses a
12 volt 1000ma adapator. There are plenty of them lying around from
when people upgraded to NGN or 802.11N.
I just took a DC adaptor and removed the components that coverted the
AC to DC. I did that for some modems that needed AC but came without
adaptors.
You could also try YS Metronics. They probably have what you need.

I do multitasking. If that bothers you, file a complaint and I will
start ignoring it immediately.
