Oscilloscope - Dual Trace Digital - 20Mhz

This dual-trace digital oscilloscope is an essential instrument for exploring waveforms, signals, and voltage behaviours in physics and electronics classes. With a 20MHz bandwidth and two independent input channels, it provides students and educators with the capability to observe and compare electrical signals in real time. The device is housed in a compact, user-friendly design and includes features typically found in more advanced models, such as X-Y mode, sweep magnification, and TV synchronisation. Whether analysing audio signals or experimenting with AC/DC circuits, this oscilloscope provides a robust platform for hands-on learning and investigation into core principles of electricity and signal processing.

Educational Benefits:

• Offers direct observation of voltage waveforms, frequencies, and signal patterns.
• Helps students develop circuit analysis skills and understand concepts like frequency, amplitude, and phase.
• Reinforces understanding of alternating current (AC) versus direct current (DC) behaviour.
• Encourages STEM engagement through practical data visualisation and signal interpretation.

Classroom Application Ideas:

• Measure signal output from function generators or sensors in circuit-building lessons.
• Compare input/output behaviour of filters and amplifiers.
• Use in demonstration experiments involving resonance, transmission, and reflection of waves.
• Display signals from audio equipment or microcontroller projects for analysis.
