Dual channel oscilloscope with 50M sampling rate, 2MHz actual bandwidth, and 10MHz analog bandwidth. With complete trigger functions (single, normal, automatic), both periodic analog signals and non-periodic digital signals can be freely used. Wide measurement ranges design, supports measurement of voltage signals up to ±400V. Waveform measurement display function, 3.2-inch LCD display, 320 * 240 resolution, three display modes design, you can easily adjust to dual-channel oscilloscope mode, X-Y model, and current waveform display. Equipped with efficient one-button AUTO, without cumbersome adjustment to display the measured waveform. 6A current waveform measurement, 20K storage depth, support waveform compress expansion. Current waveform stepless compress, the maximum compress times 165 times, can be compressed arbitrarily to display the current change curve. Later expansion function, USB one-line connection, realize one machine multi-purpose. Support firmware upgrade, in the oscilloscope machine built-in hardware allows the premise, you can put forward your needs, which can be unlimited upgrades. Diversified use, the use of a wider ranges of areas, home appliance repairs, cellphone repairs, automotive repairs, electronic interest in DIY research and development, power source repairs, and so on.
