This is a DS211 Mini Pocket Portable Oscilloscope.

The DSO series oscilloscope is an Open Hardware pocket-size compatible 32bit digital storage oscilloscope, it based on ARM -M3, equipped with 320 x 240 colour display, SD card, USB port and recharging function. It’s compact, simple to operate; meets the basic demands of school lab, electric furniture repairment and electric engineering. As all the hardware/firmware are open for hackers, It can be also a good STM32 platform for hackers DIY Projects.

Main Highlights:

Portable:

The slim and compact design can fit perfectly inside your pocket, without losing any of the integral features found in a full-sized oscilloscope!

Powerful:

System stores files in BMP, DAT, BUF, or CSV format. Uses a built-in flash disk to save/read waveform images. Math waveforms are as follows: DATA, -DATA, Inp+D, Inp-D, -Inp. Output test signal: 10Hz—1MHz (1-2-5 sequence step). Can be used in a wide range of environments including academic, electronic maintenance, electronic engineering, etc.

LCD Screen:

The 2.8inch full-colour TFT LCD screen provides a rich display for its smaller size.

Rechargeable:

A built-in 500mAH rechargeable lithium battery provides power for your oscilloscope use, rechargeable through a mini USB port.

Large Storage:

Comes with a built-in 8MB storage for saving waveform data and images!

Application:

• 1. Outdoor maintenance (AC / DC switching power supply or inverter, elevator and building fire-fighting equipment, industrial control circuit, etc…)
• 2. Hardware maintenance or software debugging of RS232, RS485, I2C, CAN and other communications interface circuits, LED display and keyboard scan driver circuit, the brushless motor drive circuit
• 3. Analyze audio devices and circuits, electronic toys and remote control models, automotive electronics circuits
• 4. Academic use provided practice for student development of small electronic production
• 5. Observe signal changes in certain circuits (such as relay and switch contacts jitter, battery charge and discharge curve, the load transient response power supply, temperature sensor characteristic measurement, etc…)
• 6. Power supply related electronic circuits (SCR voltage regulation, power factor correction, electronic energy-saving lamps, sodium lamps, dysprosium lamp mercury xenon lamps lamp drive circuit, etc…)
