Hantek DSO-2xxx/52xx
The Hantek DSO-2xxx/52xx is a series of inexpensive USB oscilloscopes. There are five models: the low-end 2090, 2150 and 2250, and the somewhat higher-end 5200 and 5200A. They are also sold as Voltcraft, with the same models numbers. Prices range from €120 - €260.
All models are USB powered, though the standard 5V/500mA from a standard USB connection is not enough: the units come with a "Y" cable, connecting the device's USB-B port to two USB-A ports on a USB hub. Probes are included in the box, with a rating matching to the model's analog bandwidth.
Sigrok currently supports the DSO-2090, and support for the DSO-5200A is in progress.
