This digital oscilloscope is a fully functional and highly practical 2-in-1 dual-channel 50MHz oscilloscope signal generator. With 250MSa/s real-time sampling rate, it can acquire signals more quickly and accurately to display waveforms. Portable oscilloscope with full trigger function (auto/normal/single). It can perfectly measure periodic analog signals and non-periodic digital signals. This handheld tablet oscilloscope with a compact and slim body with 3.98-inch touch screen is easy to use and easy to read data and view waveforms. Equipped with EVA storage bag, easy to carry. The oscilloscope is equipped with efficient one-button automatic setting of all parameters to display the measured waveforms without tedious adjustments. Long press the AUTO button to quickly calibrate the and measure the waveforms quickly to improve work efficiency. Automotive oscilloscope has a built-in 3000 mAh lithium-ion battery, which lasts about 8 hours and has a longer service life. The Type-C interface supports data transfer and charging.
