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:

• TFT controller recognition function.

• 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.

• Adjustable vertical displacement, and with instructions.

• With automatic, regular and one-shot modes, easy to capture the moment waveform.

• 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.

• Short-circuit and open-circuit detection: can help the user find out the soldering error.

• Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.
