    DSO138 oscilloscope is a device designed to study the amplitude and time parameters of an electrical signal applied to its input, either directly on the screen, or recorded on a photographic tape.

    DSO138 Oscilloscope " is a portable digital oscilloscope with TFT display.

    Heart of DSO138 Oscilloscope " it is a 32-bit microcontroller based on the ARM 32-bit core. The maximum frequency of work is 72MHz.

    Purpose of switches and buttons on the finished DSO138 oscilloscope:

    • Switches
      • The top one switches the input operation mode:
        • grounded
        • operating mode without taking into account the DC component, or AC, or operating mode with closed input. Good for AC current measurements.
        • operating mode with the ability to measure direct current, or operating mode with an open input. Allows to carry out measurements taking into account the DC voltage component.
      • The second and third switches allow you to select the scale along the voltage axis.
    • Buttons
      1. With a short press, turns on the HOLD mode, i.e. fixation of readings on the display. when it is long (more than 3 seconds), it turns on or off the digital output mode of the signal parameter, frequency, period, voltage.
      2. Button to increase the selected parameter
      3. Button to decrease the selected parameter.
      4. Button to cycle through the DSO138 oscilloscope operating modes:
        • sweep time control, range from 10μs to 500s.
        • select the sync trigger operation mode, Auto, normal and standby.
        • the mode of capturing the synchronization signal by the trigger, on the front or rear of the signal.
        • Selects the voltage level of the sync trigger signal capture.
        • scrolling the waveform horizontally, allows you to view the signal "off-screen"
        • setting the vertical position of the oscillogram, helps when measuring signal voltages and when the oscillogram does not appear on the screen
        • reset button, just reboot the oscilloscope. There is a green LED next to the button, it blinks when the oscilloscope is synchronized.

    It's safe to say that the DSO138 oscilloscope is the "eyes" of the radio amateur. DSO138 oscilloscope allows you to see processes in dynamics. DSO138 oscilloscope " can be very useful for both novice radio amateurs and experienced people.

    Reviews of the DSO138 oscilloscope:

    Осциллограф работает отлично. Что мне в нем нравиться так это точность. Раскинул на контрольные точки и вуаля, нашел что не работает.

    Пришло быстро, доставили в Киев за один день. Вольтажи и частоты показывает достаточно точно.
