Digital storage oscilloscopes in the undergraduate laboratory

Digital storage oscilloscopes (DSOs) are now easily available to undergraduate laboratories. In many cases, a DSO can replace a data-acquisition system. Seven such experiments/demonstrations are considered: (i) families of IV characteristics of electronic devices (bipolar junction transistor), (ii) the VI curve of a high-temperature superconductor (critical currents), (iii) the speed of electromagnetic waves and losses (in a coaxial cable), (iv) diffraction patterns (one and two slits), (v) the photoelectric effect (the Einstein equation), (vi) two variants of the FranckHertz experiment (with a FranckHertz tube from PHYWE and with a thyratron), and (vii) the structure of the video signal. All the experiments are performed without a computer or additional software. An exception is the experiment with a coaxial cable, where it is necessary to build graphs of the results obtained.
