DSO138 oscilloscope suite is a suite for specialized electronic professional teaching and training， the ARM architecture (M3 processor and color TFT screen， has the circuit is simple， reliable， moderate difficulty， make the characteristic of high success rate. DSO138 suite highlights the characteristics of the oscilloscope circuit， so that the students in the study of actual production skills at the same time understanding of the structure and principle of the oscilloscope. Oscilloscope skill has good practicability， students in completing production after getting a useful tool at the same time， to learn electronic technology has a great help in the future.
Deserve special pointed out that the oscilloscope at the same time a piece of STM32 MCU with color TFT LCD display (STM32F103C8) development experiment plate， combined with jinyue electronics provide source program development kit， the user can program on the basis of the development of various function.
DSO138 oscilloscope production suite features:
For electronic production practice， the full detailed information， including circuit diagrams， production guidance and the method of instructions， troubleshooting， etc， to make a high success rate.
Components are varied， suitable for students to identify the components and into the components welding， SMT components welding training.
Students can be obtained at the same time of making a practical tool， but the audio and video synchronization， frequency switching power supply， infrared receiving emission signal waveform in many occasions， such as effective observation measurement， increase the interest in learning， enhance learning effect.
Suite USES the ARM architecture (M3 processor (STM32F103C8)， and includes a 2.4 inch TFT color display， can be used as the ARM development test plate.
Provide source program， have the ability to friend can be secondary development on the basis of the suite， for example it can be changed to millivoltmeter， data recorder， and so on.
Circuit is simple， reliable， the price is cheap
