نحوه استفاده از کیت DSO138
Description:
A digital oscilloscope is a complex electronic device composed of
various software and electronic hardware modules that work together to
capture, process, display and store data that represents the signals of
interest of an operator.
DSO138 was designed as a beginner kit. It contains only the basic
oscilloscope functions with no fancy features. Simplicity in structure
and easiness in assembly/operation are amongst the main highlights of
the design. For these purposes, DSO138 uses mostly through-hole parts.
The main processor of DSO138 is a Cortex-M3 ARM (STM32F103C8) from ST.
It uses a 2.4-inch TFT LCD (320 X 240 dot matrix, 262K colors) that
displays waveforms.
By contrast, a digital oscilloscope first samples the waveform and
converts it into a digitally coded signal by an analog-to-digital
converter. The oscilloscope processes this digital signal to reconstruct
the waveform on the screen. Storage in a digital format enables data
processing even by connected PC's.
