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.
The following features are common to all models (vendor specifications):
| Channels | 2 |
| Impedance | 1MΩ 25pF |
| Coupling | AC/DC/GND |
| DC accuracy | 3% |
| Vertical adjustable | Yes |
| Input protection | Diode clamping |
| EXT. input | Yes |
| Trigger slope | +/- |
| Trigger level adjustable | Yes |
| Trigger source | CH1, CH2, EXT |
| Pre/post trigger | 0-100% |
These are the differences between the models:
