Description
The Cathode Ray Oscilloscope (CRO) 20MHz is a versatile laboratory instrument designed for visualizing and analyzing electrical waveforms, suitable for both professional and educational environments.
Key Features
20MHz bandwidth, supporting a wide range of frequency measurements for electronic testing and troubleshooting.
Dual-channel input, allowing simultaneous observation of two signals with independent controls for each channel.
High sensitivity: typically adjustable from 1mV/div (expanded) or from 2mV/div to 20V/div, enabling accurate measurement of both small and large signals.
Large display: commonly employs a 6-inch square cathode ray tube (CRT) with internal graticule, providing clear and easy waveform observation.
Multiple vertical and horizontal modes including Y1, Y2, ALT, CHOP, ADD, X-Y operation for flexible waveform analysis.
Sweep time adjustment from approximately 0.1μs/div to 0.2s/div, with magnification to as fast as 20nS/div (x10 magnification).
Advanced triggering such as ALT trigger, TV-H, TV-V synchronization, trigger lock, and external trigger input to observe all types of signals stably.
Component tester function on select models, allowing simple testing of circuit components.
Maximum input voltage up to 400V (DC + AC peak), suitable for a broad range of applications.
Compact and portable design, typically around 3-8kg with dimensions near 320 x 130 x 400mm; easy to integrate into any workspace.
Applications
Accurate measurement of voltage, frequency, time intervals, and phase difference in analog and digital signals.
Use in physics laboratories, electronics workshops, quality control departments, and educational settings.
Ideal for waveform analysis, component testing, and signal comparison.
Additional Advantages
Reliable performance and high operational stability thanks to robust SMD technology and long-life switches.
Easy operation with intuitive controls and advanced synchronization features for professional users and students.
Standard accessories typically include dual probes (20MHz), power cord, and user manual for immediate setup.
This CRO 20MHz offers enhanced capabilities, making it suitable for advanced signal analysis and practical laboratory measurements in academic and industrial environments.
