An advanced undergraduate laboratory experiment is described in which a standard two-grid Franck--Hertz tube is used as a combined electron gun, drift space, and retarding potential analyzer. Electron energy spectra with a resolution better than 1 eV are obtained which show some of the energy-loss features characteristic of mercury vapor.
