Vintage Oscilloscopes
Early, General Purpose and Servicing
An oscilloscope is a measuring device that can monitor the activity of a piece of equipment at various stages. The job of the oscilloscope is to provide a analog representation of electron activity doing an electrical function. To produce this representation an oscilloscope needs a horizontal and vertical circuit like a television. When the two circuits are working together or synchronized, the result is a waveform replica of the electrical function being analyzed shown on a cathode ray tube (vintage) or liquid crystal display.
DuMont Oscilloscopes, Passaic NJ..
DuMont 164 (1937) 3 inch display with frequency response 30-30,000 Hz PRICE $64.50. Frequency base horizontal sweep.
1950s Typical Television Servicing Oscilloscope
Philco 7019 (Philco Junior) Entry Level OscilloscopeAround 1947 Philco introduced this very basic oscilloscope as part of their servicing line of equipment. Made by Waterman Products. This 2" diameter CRT scope has no horizontal or vertical position controls so the trace is always around the center, so it is not uncommon to see a burn trace line on the CRT center. Frequency response 100 KHz.
