This oscilloscope has outstanding practical features: it supports dual-channel simultaneous display (alternate/intermittent mode switching), X-Y operation, and TV synchronization function, enabling observation of TV field/line signals or two unrelated signals. The ALT trigger function ensures stable display of signals with different frequencies. The input impedance reaches 1MΩ/25pF, with a maximum input voltage of 300V (DC+AC peak). It is equipped with a 2Vp-p/1kHz calibration signal for easy probe calibration. Adopting Japanese electronic encoding switches and sealed attenuation switches, it is lightweight and durable, meeting high-precision signal measurement needs in laboratories, production lines, and other scenarios, with simple operation and stable reliability.
