Digital Storage Oscilloscopes in the Undergraduate Laboratory
Kraftmakher, Yaakov
European Journal of Physics, v33 n6 p1565-1577 Nov 2012
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 "I-V" characteristics of electronic devices (bipolar junction transistor), (ii) the "V-I" 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 Franck-Hertz experiment (with a Franck-Hertz 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.
