New features compared with v1.6 hardware
- Connectors are added between 2 PCB board.
- Modified the circuit layout of inputting part.
- Using thin-film keypad, not need the gasket any more.
- MCX precision plug probe is used.
The greatest feature of this DS0201(DSO Nano) oscilloscope is that you can update the different firmware for it ! There are many different version firmware made by hobbyist - different version has its advantage, you can choose the firmware which most suitable for you to upgrade.
Features of latest firmware v2.5
- Modified the pattern of background coordinate grid.
- Correct the grammatical errors in the boot prompt information.
- Changed UI mode of operation: use right or left button to select the menu, up and down keys to change the menu option.
- Added "FIT" adaptive function for scan synchronization mode: 1)automatically select the scan time according to the signal frequency; 2)automatically select the sensitivity of Y-axis according to the signal amplitude.
- Without SD card, you can press both "p" and "M" button to automatically save the current state as the boot state.
- Save as BMP files.
- When AUTO, the M can cancel the comparison waveform.
This package includes the DS0201(DSO Nano)v1.6, a 700mA Lithium battery(The battery can be recharged via USB)
- ARM Digital Oscilloscope DS0201 x 1
- mini-probe and clips x1
- USB Cable x1
- Nice Cloth Bag x1
If you want to save the waveform into the SD card, initial your SD card first :
1. Format SD card with FAT16
2. Download Files Model
3. Decompress it, and copy to the root folder of SD card.

Tips: This pocket oscilloscope is primarily used for applications in the following situations:
- 1. Repair common electronic equipment outside (Air conditioning or Industrial frequency inverter power supply, AC / DC switching power supply or inverter, elevator and building fire safety equipment, industrial control circuit)
- 2. Hardware maintenance or software debugging RS232, RS485, I2C, CAN and other communications interface circuits, LED display and keyboard scan driver circuit, brushless motor drive circuit
- 3. Audio equipment and circuits, electronic toys and remote control models, car repair electronic circuits
- 4. School after-school teaching practice and student development of electronic small production
- 5. Need to slow signal changes observed applications (such as: relay and switch contacts jitter, battery charge and discharge curves of the load transient response power supply, temperature sensor features measurement)
- 6. The related supply t electronic circuit (SCR voltage regulator, power factor correction, electronic energy saving lamps, dysprosium lamp mercury lamp sodium lamp xenon lights drive circuit), As for other issues such as: CPU clock, RAM access, bus and USB or Ethernet signal measurement, high frequency and the video circuitry and the need to use FFT for signal analysis and so on occasion, The oscilloscope valued less than $1000 are not necessarily qualified for these. We advice to buy high-end oscilloscope! Deserves special mention is this pocket-sized internal battery-powered oscilloscope can be used, so in the field measurement, Ground is completely suspended, can be completely the same as multimeters, which measure what point, do not consider the issue of ground isolation.
