DSO-153 is a highly practical and cost-effective handheld oscilloscope launched by our company, targeting the maintenance industry and development education industry. This oscilloscope has a real-time sampling rate of 5MS/s, 1MHz bandwidth, and complete triggering function (single, normal, auto). It can be used freely for both periodic analog signals and non periodic digital signals, and can measure up to ± 400V voltage with an efficient one click AUTO, which can display the measured waveform without complicated adjustments. In addition, it also comes with multiple functions signal generator (10KHz). Equipped with a 2.8-inch 320 x 240 resolution HD LCD screen and a built-in 1000mAh high-quality lithium battery, it can be used for about 4 hours when fully charged.
