Product Overview
The YB43020 dual-trace quad-display oscilloscope is a high-performance general-purpose testing instrument featuring advanced SMT technology and imported digital encoder switches, which significantly enhance stability and operational comfort. With dual-channel input and four-trace synchronous display capabilities, it can simultaneously observe two independent signals, making it ideal for electronic circuit debugging, educational experiments, and industrial inspections. Its lightweight design (6.5kg) and compact dimensions (130×285×285mm) ensure portability for lab or field use. 37
Key Performance
The device offers a bandwidth of DC-20MHz (-3dB) and AC 10Hz-20MHz (-3dB), with deflection coefficients ranging from 2mV/div to 10V/div (±3% accuracy). The ×5 magnification function enables high-sensitivity measurements. Adjustable sweep time coefficients (0.1μs/div-0.2s/div, 20 steps) support diverse triggering modes including alternate, single-shot, and TV synchronization (TV-H/TV-V). The unique trigger lock feature automatically synchronizes signals without manual adjustment. Built-in 1kHz±1% calibration signals and 50Hz sine wave output facilitate self-checking and auxiliary measurements. 31924
Technical Features
Both vertical and sweep systems utilize high-durability imported encoder switches (6-10x longer lifespan than mechanical switches), ensuring smooth operation and reliability. Full-band triggering with alternate expansion allows simultaneous display of normal (×1) and magnified (×5) waveforms. The auto-focus system dynamically adjusts focus levels, while scale illumination supports observation in low-light conditions. Input ports feature 400V(DC+ACp-p) overvoltage protection for safe operation in diverse environments. 3925
Applications
This instrument is widely used for signal analysis in electronics engineering, communication equipment maintenance, and automated control system debugging. Its TV signal synchronization is particularly suited for broadcast device servicing. In education, dual-channel quad-display aids in waveform comparison for circuit timing studies. Industrial applications benefit from its robust anti-interference design in electromagnetically complex settings. 117
