Features: The oscilloscope has up to 20MS/s real-time sampling rate and a 5MHz analog bandwidth. Equipped with high efficiency one button AUTO, the measured waveform can be displayed without complicated adjustment. 2.4 inch color display screen, 320*240 resolution, displays data clearly for easily reading. Day mode and night mode can be changed according to your own preferences. Built in 1500mAh rechargeable lithium battery can be continuously charged for 3 hours at one time. Memory compression technology, waveform refresh screen does not flicker. Extremely convenient and fast waveform storage function. Built-in 16M storage space, the maximum storage of 500 waveform pictures. Powerful waveform file manager, support thumbnail browsing, viewing, details view, flip, delete and other functions. High measurement voltage range, 1X can measure 0~40V, 10X can measure 40~800V. Up to 11 parameters measurement: VPP, Vmax, Vmin, Vavg, Vrms, Frequent, Duty+, Duty-, Time+, Time-, Time. At any time, the waveform display (pause function) is frozen. Complete triggering function (single, normal, automatic).
