14 kinds of waveform measurements, free measurement response: sine wave, square wave, triangle wave, CMOS wave, half wave, full wave, staircase wave, trapezoidal wave, noise wave, exponential rise and fall, logarithmic rise and fall, five-line pulse wave, multi-tone, Lorenz.One key automatic regulation: After pressing the "AUTO" key, the oscilloscope will automatically measure the amplitude and frequency of the waveform, and automatically adjust the horizontal scale and vertical scale so that the waveform is displayed in the middle of the screen.Full trigger mode: automatic trigger will automatically trigger periodic signals, such as sine waves, normal trigger can test digital logic signals, such as infrared remote control signals, single trigger can test unexpected non-periodic signals, such as car ignition signals.Infinite Persistence Mode: With persistence mode, you can capture occasional waveforms. Use persistence to measure noise and jitter, display worst-case waveform change conditions, find timing violations, or capture rare events.Stable tough performance: waveform movement, waveform extension, waveform save, waveform view, waveform lock, reference waveform.
