Vintage tektronix oscilloscope values

In the last quarter of the 19th century, William Crooks discovered the visual effect cathode rays have inside a vacuum tube. In , J. Thompson discovered the cathode ray through his experiments but due to the extremely high voltages required, these early findings were restricted to the laboratory. In the 's Western Electric developed a cathode-ray tube CRT that ran on relatively low voltages compared to these earlier experiments.
