Power supply comparison
This is an alphabetically ordered table of various (programmable) power supplies with PC connectivity via USB, RS232, GPIB, and so on. We do not list devices without PC connectivity, as those are not really useful for sigrok.
This page lists commercial and non-commercial devices with a short overview of their capabilities. We list all kinds of devices here, not only those supported by sigrok.
You should not use the information here as the sole source for any buying decisions, this is just meant for informational purposes. Please carefully check the vendor websites if you intend to buy any hardware.
