Principles of Digital Oscilloscope

      Digital oscilloscope using data conversion from analog measurement to digital. Analog signal measurement is digitalized by hi-speed ADC. This ADC is time base controlled by a microcontroller, as user need. This digitalized data then being displayed on LED matrices by a microcontroller that controlled  horizontal scanning circuit and the appropriate magnitude signal data. This principle is shown at following figure.
