DSO138 2.4″ TFT LCD Digital Oscilloscope

Product Description

DSO138 2.4″ TFT LCD Digital Oscilloscope

Description:

– This DSO138 digital oscilloscope kit adopts ARM Cortex-M3 processor and 2.4-inch TFT screen. It is easy and reliable for the operation of the circuit.
– This is soldered (assembled), can be used directly. It can be used as an ARM test development board; It can be a secondary development based on this kit, for example it can be changed to Millivoltmeter, data logger.
– Adjustable vertical movement and with instructions.
– With automatic, regular and one-shot modes, easy to capture the waveform of the moment.
– Trigger available uphill or downhill.
– Observable previous trigger waveform (negative delay).
– Can freeze the waveform display at any time (HOLD function).
– It is supplied as a 1 Hz / 3.3 V square wave test signal source.
– With digital display of waveform parameters, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
– Waveform storage function: it will not lose the waveform after powering off.
– Short circuit detection and open circuit: can help the user to find out the welding error.
– TFT controller recognition function.
