A Brief History of the Oscilloscope

Scroll through the milestones that shaped how we see electricity — from cathode rays to software-defined instruments.

Lissajous Figure Generator

Connect two signals to the X and Y inputs and watch parametric curves emerge. Lissajous figures reveal frequency ratios and phase relationships at a glance.
