Hantek DSO-2xxx/52xx

The Hantek DSO-2xxx/52xx is a series of inexpensive USB oscilloscopes. There are five models: the low-end DSO-2090, DSO-2150 and DSO-2250, and the somewhat higher-end DSO-5200 and DSO-5200A. They are also sold as Voltcraft or Protek (rebranded) device, with the same models numbers (example: Voltcraft DSO-2090). 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 the model's analog bandwidth (see table below).

sigrok currently supports the DSO-2090, and support for the DSO-5200A is in progress.

Protocol

All Hantek DSO-XXXX USB scope models use a very similar USB protocol, as described below.

TODO: List USB VID/PIDs, too.
