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.
Hardware
The following features are common to all models (vendor specifications):
| Feature | Value |
|---|---|
| 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:
| Feature | DSO-2090 | DSO-2150 | DSO-2250 | DSO-5200 | DSO-5200A |
|---|---|---|---|---|---|
| Bandwidth | 40MHz | 60MHz | 100MHz | 200MHz | 200MHz |
| Single-shot bandwidth | DC to 40MHz | DC to 60MHz | DC to 100MHz | 80MHz | 100MHz |
| Max. sample rate | 100MS/s | 150MS/s | 250MS/s | 200MS/s | 250MS/s |
| Vertical resolution | 8 bit | 8 bit | 8 bit | 9 bit | 9 bit |
| Buffer size | 10KiB-32KiB/channel | 10KiB-32KiB/channel | 10KiB-512KiB/channel | 10KiB-14KiB/channel | 10KiB-512KiB/channel |
| Gain range | 10mV-5V, 9 steps | 10mV-5V, 9 steps | 10mV-5V, 9 steps | 10mV-10V, 10 steps | 10mV-10V, 10 steps |
| Timebase range | 4ns-1h, 38 steps | 4ns-1h, 38 steps | 4ns-1h, 38 steps | 2ns-1h, 39 steps | 2ns-1h, 39 steps |
| Shipped probes | ? | ? | ? | ? | Protek PP-200 |
Protocol
All Hantek DSO-XXXX USB scope models use a very similar USB protocol, as decribed below.
TODO.
TODO: List USB VID/PIDs, too.
