Test and Measurement

The usefulness of an oscilloscope is not limited to the world of electronics. With the proper transducer, an oscilloscope can measure all kinds of phenomena.XYZs of Oscilloscopes - Tektronix

A Tektronix model 475A portable analogue oscilloscope, a very typical instrument of the late 1970s. This dual-trace, dual-sweep instrument had a horizontal bandwidth of 250 MHz, a maximum vertical sensitivity of 5 mV per division, and maximum (unmagnified) horizontal sweep speed of 10 ns per division. - Oscilloscope - Wikipedia
