Musktool-J4569 Dual-trace Analog Oscilloscope, Universal Dual-trace Teaching 20MHz
Product Overview
A versatile teaching-grade oscilloscope designed for secondary school physics experiments, vocational education, and electronic training. Compliant with the National Education Commission's JY0011-90 industry standard, it offers 20MHz bandwidth for basic electronic signal measurement while combining intuitive operation with durability. This tool is ideal for group experiments and entry-level circuit debugging. |
Product Features
Dual-trace measurement capability Equipped with 2 independent channels, supporting CH1/CH2 single-channel display and ALT (alternating) and CHOP (intermittent) dual-track synchronous display. It enables simultaneous observation of two unrelated signals (e.g., comparing input/output waveform differences) and provides signal superposition (ADD) and CH2 inversion functions. Band and high sensitivity Frequency response DC~20MHz (±3dB), rise time ≤17.5ns, can capture audio, low-frequency digital signals and analog circuit waveforms; Vertical sensitivity ranges from 5mV/div to 5V/div (10 steps in 1, 2, 5 order), with an accuracy of ≤3%. When combined with a ×10 expansion function, it can measure extremely weak signals. Live Trigger and Scan System The trigger source supports CH1, CH2, power (LINE), and external trigger (EXT), with polarity switching capability. It offers sensitivity as low as 0.5DIV (20Hz~2MHz) and features TV field/line synchronization with automatic lockout to ensure waveform stability. Scanning frequency 0.2μs/div~0.2S/div (19 bands), which can reach 20ns/div after ×10 expansion, suitable for high-frequency signal observation。 Instructional Adaptation Design Equipped with a 6-inch cathode-ray tube (CRT) featuring green and blue displays, it offers an effective observation area of 8×10DIV with clear markings for easy reading. The fully-encoded scanning switch enables 360-degree lossless rotation, featuring Z-axis fade-out and CH1 signal output, ideal for teaching demonstrations and troubleshooting. It features a built-in 1kHz, 2Vp-p square wave calibration signal, enabling instant calibration upon startup and simplifying experimental setup. |
