Portable digital oscilloscope, multimeter + signal generator three in one, dual-channel oscilloscope, signal generator, 50 MSP and 12 MHz analog bandwidth

General Description

This versatile 3-in-1 instrument combines an oscilloscope, a multimeter, and a signal generator. It is equipped with a built-in lithium-ion battery, making it very flexible to use.   As an oscilloscope, it features a high sampling rate of 50 MSPS and a wide 12 MHz bandwidth, ensuring accurate and detailed waveform capture. This makes it particularly well-suited for analyzing complex signals in automotive repair, electronic circuit testing, and equipment maintenance. Users can adjust the signal sensitivity to simulate various conditions or test settings, which is essential for troubleshooting and calibrating electronic equipment in different industries. The waveform hold function allows for waveform capture and analysis, and its large storage capacity facilitates the documentation and comparison of numerous measurement values.   As a multimeter, it supports current, voltage, resistance, capacitance, frequency, duty cycle, diode, and continuity testing, with a maximum measurement range of up to 1600 VPP. This wide measurement range and multiple functions make it applicable to a variety of applications, from basic electrical checks to advanced electrical system diagnostics. The backlit LCD display ensures good readability of real-time data and stored information, even in challenging lighting conditions. Automatic or manual range switching optimizes the user experience.   As a signal generator, it can produce the electrical signals needed to test and calibrate other circuits or equipment.
