Latest improvements!
DSO138 oscilloscope can already directly display various parameters of the waveform, including frequency, period, pulse width, duty cycle, maximum value, minimum value, average value, peak-to-peak value and effective value, which is of great help to intuitively understand the waveform characteristics. And the effective value displayed is the true effective value, not affected by the shape of the waveform.

DSO138 oscilloscope production kit features:

Facing electronic production training, the explanation materials are complete and detailed, including circuit diagrams, production instructions, instructions for use, troubleshooting methods, etc., and the production success rate is high.
The variety of components is suitable for students to conduct component recognition, in-line component welding, and patch component welding training.
Students can obtain a practical tool at the same time of production, which can effectively observe and measure the signal waveforms of audio, video synchronization, low-frequency switching power supply, infrared receiving and transmitting and many other occasions to increase learning interest and improve learning effect.
The kit uses the ARM Cortex-M3 processor (STM32F103C8) and contains a 2.4-inch color TFT display, which can be used as an ARM development test board.
The circuit is simple and reliable, and the price is low

With waveform parameter digital display, the parameters that can be displayed are: frequency, period, pulse width, duty cycle, maximum, minimum, average, peak-to-peak value, effective value
Save / recall the waveform, the shutdown waveform does not disappear

To turn on / off the display of waveform parameters:
place the cursor in the time base position and long press the [OK] key.
Method of saving waveform:
press [SEL] and [+] keys at the same time.
To recall the saved waveform: press the [SEL] and [-] keys at the same time.
To enter the test mode:
hold down [OK] and then press the [RESET] key, if you see the LED flashes quickly, it means that there is a short circuit in the PB or PC port of the microcontroller (these ports include the connection to the LCD) Remove after exiting; if you see the LED flashing with a period of about 4 seconds, you can use the voltmeter to find the possible open circuit in the connection line related to the microcontroller port
