What is Sampling Oscilloscope ?

Sampling Oscilloscope Definition

A sampling oscilloscope is defined as an advanced type of digital oscilloscope designed to sample high-frequency waveforms by capturing multiple data points.

Functioning of Sampling Oscilloscope

It operates by collecting samples from successive waveforms and reconstructing the complete waveform for display, useful for observing fast electrical signals.

Sampling Methods

There are two primary sampling methods: real-time sampling, which captures transient events, and equivalent sampling, which works with repetitive waveforms.

Real-Time Sample Method

This method captures high-frequency transient events in one sweep, requiring high-speed memory to store the data.

Equivalent Sample Method

This method relies on repetitive waveforms, using either random or sequential sampling to improve accuracy in signal capture.
