ARM DSO 203 Nano Pocket-Sized Digital Oscilloscope (Black Metal case - not easy to break) (Please note: there are similar products in the market that come w/ black plastic case which is not good as metal case.) 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. DSO202 is a pocket size digital storage oscilloscope fulfills basic electronic engineering requirements. It is has a dual trace three lines, new kind of system interface, capacitive convenient operation. You can easily operate it with the gestures of one-click, double-click, press and slide. The Aluminum shell is very fashionable. It is equipped with 320*240 color display, 8M Memory Card (U Disk), and chargeable Lithium batteries. The thickness is 11mm only! The volume is small enough to take it anywhere. It can meet the demands in many fields, such as, school experiment, electronic repairing and electric engineering.

But it does work a lot better than the crappy scrollers on DSO Quad. The early application seems to be a bit unresponsive at times, but is already a lot better than the original DSO Quad application ever became.
