    Оscilloscope - a device designed for the study of amplitude and time parameters of the electric signal applied to its input, either directly on the screen or recorded on Photowire.

    Set «DSO138 2,4" TFT digital oscilloscope with his hands» is a constructor for the assembly of a digital oscilloscope.

    The circuit board, part of the set « DSO138 2,4" TFT digital oscilloscope with his hands», double-sided,  the board bear the symbols installed elements. The board is pre microcontroller STM32F103C8. This is a 32 bit microcontroller based on the ARM 32-bit kernel. The maximum operating frequency of 72MHz,

    The assembled oscilloscope is shown in Figure.

    The purpose of switches and buttons on the finished instrument:

    • Switches
      • The top switch mode of input:
        • grounded
        • operation without constant component, or AS, or operation with a closed entrance. Well suited for the measurement of alternating current.
        • mode to measure DC mode or open access. It allows measurements at constant voltage component.
      • The second and third switches allow you to select the scale of the voltage axis.
    • Buttons
      1. A short press toggles HOLD, ie fixing readings on the display. at length (more than 3 seconds) enables or disables the digital output signal parameter, frequency, period, voltage.
      2. button to increase the selected parameter
      3. button to reduce the setting.
      4. button busting modes:
        • Time Management sweep range 10mks to 500sek.
        • select the profile of the trigger timing, auto, normal and waiting.
        • capture mode synchronization signal trigger along the front or rear signal.
        • Select the level of stress capture trigger signal synchronization.
        • Scroll waveform horizontally, you can view the signal "off screen"
        • setting the waveform position vertically, helps with measuring the voltage of the signal waveform and when not intermeddle on the screen ...
        • the reset button, simply restart ostsillografa.Ryadom button has a green LED, it blinks when synchronized oscilloscope.

    It is safe to say that oscilloscope is the "eye" hams. This device rarely has high accuracy, unlike the multimeter, but allows to see the processes in dynamics. Set «DSO138 2,4" TFT digital oscilloscope with his hands » can be very useful for both beginner radio amateurs, and people with experience
