WebMay 18, 2024 · Electromechanical Oscillographs: Automating Waveform Generation. The first fully automated waveform generator was invented by Édouard Hospitalier, French engineer, in 1902. Known as the Hospitalier Ondograph, the device recorded a waveform by moving a pen across a drum of paper, in reaction to measurements from a galvanometer.

WebPen oscillographs are self-balancing recorders with servomotors that operate in proportion to the amplitude of input signals to move pens and thereby record signal data. They have a response speed on the order of dozens of hertz, but their use of mechanical means to represent amplitude imposes limits on that speed, and ink-type variants require ...
