Description:
This DSO138 digital oscilloscope kit adopts ARM Cortex-M3 processor and with 2.4-inch TFT screen.
It's easy and reliable for circuit operation. It can display frequency, period, pulse width, duty ratio, max. / min. / avg. / peak-peak / virtual values.

Features:
• This kit uses ARM Cortex-M3 processor, and includes a 2.4-inch color TFT display screen, can be used as ARM test development board
• With automatic, regular and one-shot modes, easy to capture the moment waveform
• Can be secondary developed to millivoltmeter, data loggers
• Adjustable vertical displacement, and with instructions
• Available rising or falling edge trigger
• Observable previous trigger waveform (negative delay)
• Can freeze at any time waveform display (HOLD function)
• Comes 1Hz / 3.3V square wave test signal source
• Waveform storage: not lose the waveform after power off
• Short-circuit and open-circuit detection: can help the user find out the soldering error
• TFT controller recognition function
