DSO138 DIY 2.4 inch Oscilloscope Kit

The DSO138 DIY oscillator kit is integrated with an ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, that can be used as the ARM test development board. This is DSO138 2.4″ TFT Handheld Pocket-size Digital Oscilloscope Kit. It features automatic, regular, and one-shot modes, easy to capture the moment waveform.

It's easy and reliable for circuit operation. This DSO138 oscilloscope kit can display frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.

This boost converter is a great match for the DSO138 oscilloscope kit. It can be connected directly to the DSO138 motherboard(not included), making the DSO138 oscilloscope to be a portable oscilloscope for better use.

Features:

  • This kit uses an ARM Cortex-M3 processor (STM32F103C8) and includes a 2.4-inch color TFT display screen, which can be used as the ARM test development board.
  • Adjustable vertical displacement, and with instructions.
  • Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.
  • Comes 1Hz /3.3V square wave test signal source.
  • Available rising or falling edge trigger.
  • With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
  • With automatic, regular, and one-shot modes, easy to capture the moment waveform.
  • Observable previous trigger waveform (negative delay).
  • Can freeze at any time waveform display (the HOLD function).

1. How to calibrate a DSO138 Oscilloscope Kit?

  • There is always some capacitance between the oscilloscope input and the grounded probe, which must be calibrated to better measure high frequency signals. This can be done using built-in test signals. To do this, follow the steps below.
    1. Connect the red clip to the test signal connector and leave the black clip non-connected. 
    2. Set [SEN1] switch to 0.1V and [SEN2] switch to X5. Set [CPL] switch to AC or DC.
    3. Set the timebase to 0.2 ms. If the waveform is not stable, adjust the trigger level to get stable readings.
    4. Turn C4 (capacitor trimmer) with a small screw driver so that the waveform displays sharp right angle.
    5. Set the [SEN1] switch to 1V, the [SEN2] switch to X1, and leave the other settings unchanged. Adjust C6 to display a sharp square wave.

2. How to use a DSO138 Oscilloscope?

  • Follow the below mentioned steps to use a DSO oscilloscope.
    1. Hold down SW4 and press RESET to enter test mode. 
    2. If the LED flashes fast, it means there is a short circuit on the PB or PC pin. First you need to figure out your shorts.
    3. If the LED is blinking slowly, use a voltmeter to check for any suspect open pin related connections. If no voltage change is seen. where you connect to the port pin, Open between the point and the port pin.
