DSO 138 oscilloscope circuit boards components are pre-soldered, no need soldered by yourself.
DSO 138 Mini Oscilloscope uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board.Can freeze at any time waveform display (HOLD function).
DSO 138 Oscilloscope With automatic, regular and one-shot modes, easy to capture the moment waveform. Available rising or falling edge trigger. Observable previous trigger waveform (negative delay).
This oscilloscope With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values. Waveform storage function: will not lose the waveform after power off.
Adjustable vertical displacement and with instructions, which increase the likelihood of adding different features or developing new applications on the hardware for users.
