Thisis readytouse handheldoscilloscope kit powered byARM Cortex-M3 processor (STM32F103C8) and includes a 2.4-inch TFT display. The DSO138 oscilloscope kit can display frequency, period, pulse width, duty ratio, and max/min/avg/peak/virtual values.

Features:

• Observable previous trigger waveform (negative delay).
• Can freeze at any time waveform display (HOLD function).
• Comes 1Hz /3.3V square wave test signal source.
• 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.
• TFT controller recognition function.
