Oscilloscope fast capture/update rate: How useful is it?

Article by John Ong | 11 June 2025 Fast Acquire & Display Oscilloscopes Recently, I encountered an electronics waveform that resembled composite video signals—something I haven’t seen since the days of analog TV. I started off using an entry-level oscilloscope boasting a capture/update rate in excess of 100,000 waveforms per second. I stared at the […]

Oscilloscope vs. Spectrum Analyser: Understanding the Key Differences

In modern electronics, signal analysis tools are crucial for testing and diagnosing complex systems. Amongst these tools, oscilloscopes and spectrum analysers are widely used by engineers and technicians. While both devices help evaluate electrical signals, they are designed for distinct purposes: oscilloscopes focus on time domain analysis, and spectrum analysers specialise in frequency domain analysis.
